My mac book pro 2010 started acting up last night. Wifi was slow and certain letters were not displayed properly. I restarted the computer and it failed to boot up again.
I took the drive from the bad computer and put it in a working mac book pro 2013. The computer had issues booting up initially. After restarting the NVRAM by holding command + option + p + r, I can now access the recovery screen. I tried selecting the start up disk. I get the following error message, "you cant change the startup disk to the selected disk running bless to place boot files failed".
I tried to reinstall high sierra, but I get a com.apple.osinstall error -3 error after restart. What should I try next to troubleshoot the issue?
