-
I got my MacBook repaired for the first time because of Bluetooth connection problem.
-
After the repair, I suddenly had a problem that wasn't there. The app in use is often turned off.
-
I had it repaired one more time, but there's still a problem.
-
It goes off more than 10 times per hour. After Apple's repair, there was a problem that didn't exist.
-
I visited the Apple store one more time, and he told me that the app I was using didn't seem to follow the Bigsur version. I checked it but my coworker's Bigsur works well.
He tried to avoid Apple's responsibility, saying that it was not a hardware issue until the end, but a software issue that I was using.
The key point is that there is a problem after I have been repaired.
How can I solve this...
