Things to Note
Consistency of Packaging Box/Computing Box/System ID
Are the three codes consistent? If they are different, the device has been opened.
Checking the Number of Power Cycles
Normally, the fewer cycles, the better (mine had two).
Checking Warranty Date on the Official Website
Here (to check the purchase date from the seller).
Absolutely Do Not Use Any Optimizers
Especially for those who have just switched from Windows and have “obsessive-compulsive disorder” when it comes to cleaning.
I already knew that Mac doesn’t need cleaning and this was a new device, but I still couldn’t resist trying out the best disk cleaner, CleanMyMac.
After using it, I noticed that the temperature went up to more than 90 degrees, so I checked for Mac’s cooling issues.
Later, I found that there was a process that was consuming a lot of CPU.
Then I saw that many icons on the dock became transparent (with text and clickable, but restarting did not solve the issue).
After searching on Google, I found out that many people actually had to reinstall the system.
And the culprit turned out to be CleanMyMac.
A bloody lesson, it’s true that “if you don’t court death, you won’t die!!!”.
Solution to the transparent icons:
1 | rm ~/Library/Application\ Support/Dock/*.db; killall Dock |
After clicking on the dock, it should be restored; if not, try removing it and dragging it back in.
