It's inevitable that the performance of Mac computers drops over time. The most obvious symptoms are the slow start-up and the dreaded multicolored wheel that spins as soon as several applications are opened. If your computer is affected, now is the time to take a few minutes to refresh the system and give it back some of its initial vigor.

- Press Users and Groups.
- Click on the tab Opening hours.
- Select each application you want to prevent from launching at session startup.

Delete unnecessary filesIt is advisable to have at least 10% free space on your hard drive, with an absolute minimum of 5GB. To do this, it is important to regularly delete unnecessary files that clutter your memory: browser cache, email attachments stored locally, imovie or iTunes archives...

Delete your files or apps that are taking up spaceIt is your "useful" files that take up most of the disk space. To make room, you can sort through large archives (movies, videos, photos, music, etc.), track down duplicates and consider an external hard drive or online storage to relieve your Mac's internal hard drive.
Similarly, you can uninstall applications that you no longer use, as follows:

- Press Applications dans la colonne de gauche.
- Find the software you want to remove from the list and tap it once.
