12/8/2020 Mac Performance App Automatic
This article is for network administrators and other people who manage their own network. If you're trying to join a Wi-Fi network, one of these articles should help:
Before changing the settings on your router
See how much energy your Mac is using. You can find out how much energy your Mac is using, and see which apps or processes are using the most energy. How to monitor overall energy use. See real-time CPU, network, or disk status in the Dock. Let us know in the comments below if you have any other techniques for improving the performance of your Mac. You can also find some useful Mac apps and utilities on Envato Market. They can help you be more efficient and productive on your Mac, accomplishing everything from compressing images to cleaning up code.
Router settings
To ensure that your devices can reliably reconnect to your network, apply these settings consistently to each Wi-Fi router and access point, and to each band of a dual-band, tri-band or other multi-band router.
Network name (SSID)
A single, unique name (case sensitive)
The Wi-Fi network name, or service set identifier (SSID), is the name your network uses to advertise its presence to other devices. It's also the name that nearby users will see on their device's list of available networks.
Use a name that's unique to your network, and make sure all routers on your network use the same name for every band they support. For example, don't use common names or default names, such as linksys, netgear, dlink, wireless or 2wire, and don't give your 2.4 GHz and 5 GHz bands different names.
If you don't follow this guidance, your devices may not connect reliably to your network, to all of the routers on your network or to all of the available bands of your routers. And devices that join your network are more likely to encounter other networks that have the same name, and then automatically try to connect to them.
Hidden network
Disabled
A router can be configured to hide its network name, or SSID. Your router may incorrectly use 'closed' to mean hidden, and 'broadcast' to mean not hidden.
Hiding the network name doesn't conceal the network from being detected or secure it against unauthorised access. And because of the way devices search for and connect to Wi-Fi networks, using a hidden network may expose information that can be used to identify you and the hidden networks you use, such as your home network. When connected to a hidden network, your device may display a privacy warning due to this privacy risk.
To secure access to your network, use the appropriate security setting instead.
Security
WPA3 Personal for better security, or WPA2/WPA3 Transitional for compatibility with older devices
The security setting defines the type of authentication and encryption used by your router, and the level of privacy protection for data transmitted over its network. Whichever level of security you choose, always set a strong password to join the network.
Settings that turn off security, such as None, Open or Unsecured, are strongly discouraged. Turning off security disables authentication and encryption and allows anyone to join your network, access its shared resources (including printers, computers and smart devices), use your Internet connection, and monitor data transmitted over your network or Internet connection (including the websites you visit). This is a risk even if security has been turned off temporarily or for a guest network.
Don't create or join networks that use older, deprecated security protocols such as WPA/WPA2 Mixed Mode, WPA Personal, TKIP, Dynamic WEP (WEP with 802.1X), WEP Transitional Security Network, WEP Open or WEP Shared. These are no longer secure, and they reduce network reliability and performance. Apple devices display a security warning when joining such networks.
MAC address filtering, authentication and access control
Disabled
When this feature is enabled, your router can be set up to only allow devices that have specified media access control (MAC) addresses to join the network. Reasons why you shouldn't rely on this feature to prevent unauthorised access to your network:
To secure access to your network, use the appropriate security setting instead.
Automatic firmware updates
Enabled
If possible, set your router to install software and firmware updates automatically as they become available. Firmware updates can affect the security settings available to you, and they deliver other important improvements to the stability, performance and security of your router.
Radio mode
All (preferred),or Wi-Fi 2 through Wi-Fi 6 (802.11a/g/n/ac/ax)
These settings, available separately for the 2.4 GHz and 5 GHz bands, control which versions of the Wi-Fi standard the router uses for wireless communication. Newer versions offer better performance and can support more devices concurrently.
It's usually best to enable every mode that's offered by your router, rather than a subset of these modes. All devices, including older devices, can then connect using the fastest radio mode they support. This also helps reduce interference from nearby legacy networks and devices.
Bands
Enable all bands that are supported by your router
A Wi-Fi band is like a road that data can flow down. More bands provide more data capacity and performance for your network.
Channel
How can i open a downloaded app on mac. Auto
Each band of your router is divided into multiple, independent communication channels, like different lanes on a road. When channel selection is set to automatic, your router will select the best Wi-Fi channel for you.
If your router doesn't support automatic channel selection, choose whichever channel performs best in your network environment. That varies depending on the Wi-Fi interference in your network environment, which can include interference from any other routers and devices that are using the same channel. If you have multiple routers, configure each one to use a different channel, especially if they are close to each other.
Channel width
20 MHz for the 2.4 GHz band
Auto orall widths (20 MHz, 40 MHz and 80 MHz) for the 5 GHz band
Channel width specifies the size of 'pipe' available to transfer data. Wider channels are faster but more susceptible to interference, and also more likely to interfere with other devices.
DHCP
Enabled, if your router is the only DHCP server on the network
Dynamic host configuration protocol (DHCP) assigns IP addresses to devices on your network. Each IP address identifies a device on the network and enables it to communicate with other devices on the network and Internet. A network device needs an IP address, much like a phone needs a phone number.
Your network should only have one DHCP server. If DHCP is enabled on more than one device (such as on both your cable modem and router), address conflicts may prevent some devices from connecting to the Internet or using network resources.
DHCP lease time
8 hours for home or office networks; 1 hour for hotspots or guest networks
DHCP lease time is the length of time that an IP address assigned to a device is reserved for that device.
Wi-Fi routers usually have a limited number of IP addresses they can assign to devices on the network. If that number is depleted, the router can't assign IP addresses to new devices, and these devices can't communicate with other devices on the network and Internet. Reducing DHCP lease time allows the router to reclaim and reassign old IP addresses that are no longer being used faster.
NAT
Enabled, if your router is the only device providing NAT on the network
Network address translation (NAT) translates between addresses on the Internet and addresses on your network. NAT can be understood by imagining a company's post room, where deliveries to employees at the company's address are directed to employee offices within the building.
You should generally only enable NAT on your router. If NAT is enabled on more than one device (such as on both your cable modem and router), the resulting ”double NAT” may cause devices to lose access to certain resources on the network or Internet.
WMM
Enabled
WMM (Wi-Fi multimedia) prioritises network traffic to improve the performance of a variety of network applications, such as video and voice. All routers that support Wi-Fi 4 (802.11n) or later should have WMM enabled by default. Disabling WMM can affect the performance and reliability of devices on the network.
Device features that can affect Wi-Fi connections
These features may affect how you set up your router or the devices that connect to it.
Private Wi-Fi Address
If you're connecting to a Wi-Fi network from an iPhone, iPad, iPod touch or Apple Watch, find out more about using private Wi-Fi addresses in iOS 14, iPadOS 14 and watchOS 7.
Location Services
Make sure your device has Location Services turned on for Wi-Fi networking, because regulations in each country or region define the Wi-Fi channels and wireless signal strength allowed there. Location Services helps to ensure your device can reliably see and connect to nearby devices, and that it performs well when using Wi-Fi or features that rely on Wi-Fi, such as AirPlay or AirDrop.

On your iPhone, iPad or iPod touch:
Auto-Join when used with wireless carrier Wi-Fi networks
Wireless carrier Wi-Fi networks are public networks set up by your wireless carrier and their partners. Your iPhone or other Apple mobile device treats them as known networks and connects to them automatically.
If you see a ”Privacy Warning” under the name of your carrier's network in Wi-Fi settings, your mobile identity could be exposed if your device were to join a malicious hotspot impersonating your carrier's Wi-Fi network. To avoid this possibility, you can prevent your iPhone or iPad from automatically rejoining your carrier's Wi-Fi network:

Too often people upgrade only to find their problems begin, or persist.
If you need help with a slow Mac running a Mac operating system, please be prepared to answer these questions, or find out how to get the answer to these questions.
Etrecheck, a software written by one of our fellow contributors, is a software that has been useful in isolating many of the issues below:
Look at these troubleshooting steps. Find
1. If MacKeeper was installed, and if it is, remove it with the instructions in this tip:
2. If any other system cache cleaner is installed. If there is, contact the vendor on how to remove it.
3. Mega app store. If the possibility your hard drive is over 85% full exists.
4. If Spotlight hasn't finished indexing. (does not apply to 10.3.9 or earlier). Clicking on the icon in the upper right that looks like:
(it may have a different color), will reveal if Spotlight is indexing, or is ready to search. Going to Apple menu -> System Preferences -> Spotlight -> Privacy will show if a specific folder or drive is ignored by your last Spotlight index.

5. If you are attempting to multitask with a Time Machine backup going on. (does not apply to 10.4.11 or earlier)
6. If permissions are damaged. Often a problem when using pre-2006 Classic environment on PowerPC Macs. See #10 how to identify Macs.
7. If third party software or drivers hasn't been tested with your installed operating system. https://newavid752.weebly.com/flip-clock-app-mac.html.
8. If You migrated data from a different Mac CPU type. I.e. from PowerPC to Intel, or Intel to PowerPC. See 10 on how to identify Macs.

9. If energy saver isn't giving some peripheral problems, because the peripheral doesn't understand low power mode.
10. If the possibility exists that there is marginal hardware on
Intel Macs or PowerPC Macs
Use: https://discussions.apple.com/docs/DOC-6413 to determine if you have PowerPC or Intel.
11. If you have had 4 language screens forcing you to restart your Mac, that's significant, and indicates what is known as a kernel panic.
Usually an issue relating to the hardware, though sometimes a directory may be damaged, or sometimes a bad or incompatible driver is installed.
Running the hardware test for Intel Macs or PowerPC Macs
will indicate if some RAM is bad, but not all RAM. Any errors found with it are significant.
12. If you don't have a current system, find out if a website you are visiting needs a newer plugin for Java, Flash, etc..(10.7.2 or earlier do not run a current Java. 10.6.7 or earlier do not run a current Flash. But updating to those is only necessary for a few websites. Check before updating to ensure you don't make yourself incompatible in other ways). Before updating to 10.7 or later, be sure to read this tip about compatibility first: https://discussions.apple.com/docs/DOC-6271
13. If your data is backed up from before or after the upgrade, and we can isolate other issues. Without a backup, we can't say if the solution might be worse than the problem.

https://discussions.apple.com/docs/DOC-1992 - tells you how to backup a functional system.
https://discussions.apple.com/docs/DOC-1689 - tells you how to recover a system that is not functional or able to boot so at least other issues can be
isolated.
14. Slowdown to internet applications may be due to third party router firmware not being up to date, too many machines using the router, an insecure router not using WPA2 connectivity (802.11b original Apple Airport can't use it, and it is better to get a WiFi ethernet bridge with at least 802.11g), proxy servers, and bad DNS issues which http://www.opendns.org/ can resolve. Additional WiFi related issues are documented on this tip:
15. A bad iTunes install, or one that isn't properly updated for the system may cause slow down. If you are trying to isolate that as a possibility, note the path to the iTunes Helper which is loaded in your System Preferences -> Accounts (Users and Groups in some versions of Mac OS X), Login Items (startup items in other versions of Mac OS X)
/Applications/iTunes.app/Contents/Resources
You can use the Finder's Go to Folder command in the Go menu to reload that program after removing it from your Login Items and troubleshooting the situation.

16. Peer2peer sharing software, torrent software, both make your machine into a software server. This can slowdown your overall internet. Do not get software from such sources, as most are illegal. If you have trouble finding software for your operating system, visit http://www.roaringapps.com/ if using Mac OS X 10.7 or later, or ask on this board where to find software that is legal that does what you need.
17. If your Mac is backed up, then's the time to see if a directory repair is necessary:
18. Often times, you will see the system slowdown and get a spinning color circle indicating it is busy. After a certain amount of time, if you can risk losing the data that has not been saved on the application, force quitting the application with command-option-escape key sequence is a possibility.
Mac Performance App
If command-option-escape does not work, it may indicate one of the aforementioned issues is happening. Command and Option keys may look like some variation of:
On non-Apple keyboards the Windows key usually takes the place of the Command key, and the Alt key usually the Option key. Though Microsoft has made a patch for its keyboards that forces the two keys to switch their assigned Apple keystroke, since they are in reverse orientation of the Apple keyboard. The Escape key is typically just labelled ESC.
19. You may not experience any of the above issues with games or high end graphics applications. The graphics processor unit (GPU) recommended by the developer should be the one you have installed on your computer. Any others, and speed may be an issue with those programs. It is not to be confused with RAM or your CPU.
20. Migrating data from PowerPC Macs. See first #10 to see if you had a PowerPC Mac you were migrating from. If you did, you may have brought over some drivers the Intel Mac does not understand in the Migration or Setup Assistant. If there is a chance this may have happened, you should see this tip on migration which avoids the issue:

21. Notifications can slow Mac OS X 10.9 down. Go to Apple menu -> System Preferences -> Notifications to disable those notifications you don't need.
22. iCloud syncing (in 10.7.2 and later) can slow things down. Manage iCloud through the System Preferences to ensure syncing only happens when you need it. iSync in Mac OS X 10.6 and earlier can also slow things down when you don't need it.
