If this seems like your computer, then you would possibly be brooding about replacing your computer. whenever you upgrade the macOS to the newer version, you’ll determine that the laptop is slower than before.Ĭommon signs of poor computer health include slow startup times, sluggish performance while using large apps and system crashes. This old-style disk drive is the bottleneck of your Apple Mac. The 2008-2012 MacBook Air with a non-retina screen came with a standard spinning disk drive. I tested booting from both when it had Yosemite and it went back and forth no problem.Do you have a MacBook Air? does one feel that you simply might be getting more out of it? does one long for the times when your computer was brand new? When it booted up during a snap, and ran without a hitch? Then our Mac SSD upgrade service is the service for you! This service includes our MacBook Air SSD upgrade and iMac SSD upgrade options. Question is, do you think the drive went bad or do you think i did something wrong when i upgraded to high Sierra. When restarting holding option to switch that way it has a firmware lock and, same problem, the previous owner doesn't remember it or have original receipt so I can't get past it.
But now when I try to go back the internal drive doesn't appear and will not mount in disk utility. From high Sierra I went to startup and selected the external to start up instead if internal. I also have an external harddrive running el Capitan for some legacy software I need to use still. I upgraded out to high Serra so i could run a specific editor software. Bought a used macbook pro 13" running Yosemite. I have a similar problem but was hoping for clarification.
