Chapter in this post:
If your Apple Mac is causing problems and spinning around, there can be several reasons. If the finder is too slow or if the colorful beach ball keeps popping up, this can be due to an overfilled system memory, among other things. Quite often I get queries from readers describing very strange behavior on their Macs. That's why I created this post to collect a few troubleshooting tips.
In the respective inquiries about problems with the Apple Mac, iMac or MacBook I read again and again about the same bitches that the computer makes. Often the corresponding behavior shows no regularity, so that recording, re-enactment or precise explanation of the Mac problem is difficult.
Often times, these and other problems with the Mac, macOS and individual programs can be solved with a few simple steps. I would recommend the following steps for a slow / buggy system:
Should you find any other issues, such as that the Mac does not wake up from sleep, or if the steps outlined above do not help, please contact me - for example via the contact form. Please describe the problem as precisely as possible. You can also use the search text field (on the right side of this page) to find additional help articles and instructions. Sometimes there are simple solutions to problems. Every now and then you need to reinstall OS X or macOS. If you need help on the Mac, let me know;)
