replacing ssd on MacBook pro 2017 no touchbar
My MacBook pro 2017 - no touchbar - seems to need new SSD Memory chip. Since a few days, everytime it goes to sleep, it is froze after wake up. When i restart it, there is an empty folder with a questionmark. When starting it with the Base-System (key-combination "R" and "command-key"), i try to perform Diskrepair, and it doesn't show the System Disk, but only the 2 GB Base Disk. After performing this operation a couple of times, the MB succeeded occasionally , until now, to restart correctly.
The diagnosis seems clear : Replace the SSDs. The steps don't seem too complicated (have some background in electronics). Nevertheless, 2 questions:
Question 1 : my actual OS is Ventura 13.6.9. The SSDs have 250 GB.
Can i install a larger SSD, or would that provoke problems?
Question 2 : in some posts i saw that i would need to reload an earlier system. Do i still have to do this ?
Thanks for all advices !
Cheers, Thomas
