Are you seeing slower startup or shutdown times?
It’s only normal if your Mac slows down as you add more documents and files. Of course, if your system slows down drastically, then this could be more serious than otherwise.
That said, here are 4 solutions to slow startup or shutdown times on your Mac:
1: Hard Drive Nearly Full
It’s a good thing to have 10-15% of your disk space free. Filling your Mac up to the brim will slow performance as well as write slower. This is because there are too many files apart from not finding free space on the disk. So, delete all unnecessary files. Move infrequent files to external storage.
2: Disk Integrity
Checking the physical integrity of your disk is important. Running a test will indicate whether your disk is showing signs of wearing out. For this, go to Disk Utility, select your System Disk. Then click the Verify Disk button. If there are problems, use the Repair Disk button. Of course, if you cannot repair it, then you’ll have to replace your internal disk.
3: Disk Permissions
Macs have a file permissions system for the sake of file security. It specifies who can read, write or specify what files. Yet file permissions can get corrupted due to user action or bugs. This will slow down your system. For this, select your disk in Disk Utility and then Repair Disk. You can still use this even if permissions aren’t your problem.
4: Reset PRAM
The PRAM is temporary storage on your Mac for system configuration and settings. If the settings gets corrupted, then you might have to reset it. To do this, turn off your Mac first. Turn it back on again. Now after this, hold down Command, Option, P and R.
