HOW TO RESTORE BATTERY LIFE AFTER iOS 14 UPGRADES?

CUH is a process which can appear in Activity Monitor taking up excess CPU, and is part of CorelDRAW for Mac. If that’s installed and you’re having problems, contact Corel support. If you’ve removed the app, it may need separate uninstallation, try searching for it and manually removing it.
WHY HAS MY NEW ANTI– VIRUS DISABLED MAPS?

DO I NEED TO INSTALL JAVA FOR MINECRAFT?

WHERE HAVE TOP SITES GONE?

CAN MACOS SAVE DISK SPACE USING AUTO COMPRESSION?
System files have been doing this since OS X 10.6, but this feature hasn’t been well supported for users or developers. This changes in Big Sur with the arrival of AppleArchive, although that’s not intended for use for whole volumes.
WHERE CAN I SEE WHICH APPS HAVE BEEN UPDATED?
The closest macOS comes is in System Information. Select the Installations item under Software to show updates and software installations made using installers, including system software, and from the App Store. This doesn’t include apps which use their own updaters, or which have been moved to the Applications folder.
DOES MACOS EVER CHECK MY DISK FOR MALWARE?
XProtect checks for malicious software. In 10.15 and later, this checks all software you open, not just recent downloads, against its list of known malware, which is updated every couple of weeks.
HOW BEST TO CHECK AND REPAIR MY STARTUP DISK?
Unless you’ve got a bootable external disk running the same version of macOS, start up in Recovery mode, open Disk Utility and select the startup volumes, then run First Aid.
