When i power on my new mac book pro (with touch bar) i figured out a strange problem (i think is related with my graphic card).
This is the procedure to get that issue:
- Power on my mac
- Type my credentials
- the first window i open (in this case the "spotlight" window) appears in this way: There are a lot of white pixel ...
- Then if i close the spotlight window and i open again that problem disappear.
If i restart my mac i don't have this problem. It only happen if i shut down my mac and then power on it again. In this example i used "spotlight" but happen the same with the "Finder" app.
- Intel HD Graphics 530
- Radeon Pro 450
Yes i have this issue on my interal display (external monitor never used).
NVRAMdidn't fix the problem.
After many call to "Apple Care" they figured out that my mac book pro has some hardware issues. They offer to me a substitution. Of course i said yes. In 2 weeks they will send to me a new one.
