I am installing it wrong? xD
It is literally only pressing a button to install, so nothing I can do from my side to do it wrong.
i can reproduce the crash 100% now, so it is a buggy mess of a OS.
Even PC’s are much more stable then this.
Let’s see if I can downgrade my Macbook Pro to an older OS. Else i will have to use my Macbook Pro in bootcamp.
I buy Macs because they are more stable, reliable, and longer lasting than PCs... But every device can fail.
What happened to you is random and relatively rare problem with, hopefully, just installation going "wonky". Happens sometimes and screaming and complaining gets you nowhere. If you want to fix your problem, try following:
1. Try reseting SMC and PRAM. Cannot hurt.
If the problem is not fixed:
2.
Backup any data you need to protect. Backup is something you should really, really have. All hardware and software can crash and die. All drives eventually die - my 2017 MBP SSD died after ~18 months of use; I just replaced HD in my other computer... I saw somewhere that estimated 20% of drives die within first 4-5 years - independent of OS.
3. Download the latest version of the system you currently have from App store and reinstall over existing system (aka "in place"). This usually fixed my issues caused by failed installation (happens sometimes). And it should be non-destructive for your data (note the
should there).
4. If this does not fix the problem, boot while holding cmd-R to recovery and reinstall the system - but format the system drive before installation (this is fresh installation).
This WILL wipe your data, so make sure you have may be even two backups...
Now, test if all works BEFORE moving any data and apps back... If it works, use Migration assistant to move your data, apps, and all configuration back.
If it still works, fine, you are done.
If it starts failing again, it is your configuration/Applications which may be causing issues. You will need to reinstall fresh again and move back only data - manually. And reinstall applications from original sources and after careful consideration on compatibility with the current system. You need to identify, which one is killing your machine. Somehow figure out who is causing the problems. Can be challenging - few years ago it was software with kext for weird 3G network dongle for me.
If fresh reinstall and clean system does not fix the problems, take the computer to Apple and ask for help. Sounds like hardware. They should be able to help you figure out whats wrong and what needs to be fixed.
