Popular questions
Why is my Mac so slow?
First, check Activity Monitor to see whether one app is using an unusually high amount of CPU or memory. If nothing stands out, look at your available storage and Login Items. A nearly full startup disk, an overloaded app, or too many processes launching at sign-in are more common causes of a slow Mac than the age of the computer itself.
Why does Spotify automatically open on my Mac?
Spotify usually opens at sign-in because automatic launch is enabled inside Spotify or because macOS has added it to Login Items. In Spotify, open Settings and set “Open Spotify automatically after you log into the computer” to No. Then check System Settings → General → Login Items and remove Spotify if it is listed there.
Can I delete Safari from my Mac?
Not in the same way as a regular app. Safari is part of macOS and is protected by System Integrity Protection, so trying to remove it manually can damage system files or cause it to return after an update. A safer option is to choose another default browser and delete Safari’s history, website data, downloads, and extensions.
How do I check all app updates on my Mac?
To check all installed apps in one place, open the Update section in App Cleaner & Uninstaller. It detects available updates for both App Store apps and applications installed from developers’ websites. You can also check them manually, but that requires reviewing the App Store and the update settings of each app separately.
How can I free up disk space on my Mac?
Open System Settings → General → Storage and start with the largest category you can safely control. In most cases, the quickest gains come from deleting large downloads and disk images, uninstalling apps you no longer use, removing duplicate files, and emptying the Trash. Do not delete files from the System or Library folders simply because they take up space.
