#MACOS HIGH SIERRA OPERATING SYSTEMS MAC OS X#
Mac OS X was the official naming through version 10.7, from 2001 to 2011. In fact, three terms were used at different times with reference to Apple’s operating system: Mac OS X, OS X, and macOS. No, they are essentially the same thing - just named differently.
Is there any difference between Mac OS X and macOS? In this article, we guide you through the evolution of Apple’s operating system, from the first public release in 2001 to the latest macOS Monterey announced at WWDC 2021 on June 7.
As Apple grew and strengthened the ecosystem through the years, macOS operating system version history evolved too. MomacOS is the operating system designed to run on Apple laptops and desktop computers. J'ai une copie de celui=ci sauvegardé sur un disque effectué par Time Machine.Tackle your tasks with Setapp app suite solutions. Le disque SSD ou se trouvait le OS High Sierra a été effacé, je croyais que ça irait mieux pour ré=installer en neuf.

Quand j'ouvre le Mac Pro 5,1, j'ai soit une image de cadenas sur fond gris avec un carreau pour entrer un mot de passe ou autrement c'est l'image d'une chemise de classement avec un point d'interrogation. Le mot de passe de l'ordi en question, je ne l'ai pas, ce mac pro m'a été légué et mon oncle est décédé. J'ai une clé avec High Sierra, mais ça prend les commande à entrer dans Terminal lorsque la clé est reconnu. Avec Appstore on se retrouve devant rien à la fin de l'importation, le système AppStore vérifie si c'est compatible sinon, il ne laisse rien. J'ai finalement réussi à copier High Sierra sur une clé USB.Ĭe qu'il faut savoir avant d'essayer, c'est d'utiliser Safari et ne pas laisser AppStore faire l'importation.
#MACOS HIGH SIERRA OPERATING SYSTEMS INSTALL#
Is there any sequence of key strokes that I can use to do a fresh install of High Sierra without actually being able to see what I’m doing? Or some magic cheat code I can put in to force it to only consider the external monitor as existing (ie completely ignore the main MBP one)? Such things seem possible from within the OS with normal settings but I’m not at that point just yet. Its clearly acting as an additional monitor as I can move the pointer off the left side of the screen as if there’s more screen space over there. The problem is that the installer and Recovery both want to put their windows on the original screen leaving me with a blank grey screen on the external monitor (with a functional pointer). I have a bootable installer on a USB drive for High Sierra. This time I have an external screen which gets a good signal so there is some sort of output but the main screen is totally non-functional. I have a 2011 MBP17 and its on a third or fourth failed GPU. The clean Yosemite install setup the Recover Partition on new drive and the files copied from Time Machine restored system to original state without messing with newly created Recovery partition. Shut Down, Reboot with Command-R, plug in USB drive, format new disk, load Yosemite from USB to new disk, then shut down, Restart with Command-R, then load Time Machine backup.

Sequence was full backup (I did both Time Machine and CCC to be sure)., create bootable USB installer drive (Google it, I used the Disk Utility method). Either way, setting up a bootable Install USB drive (8 gig minimum for Yosemite) was necessary. When encrypted (Time Machine and CCC clone of drive), the Recovery HD is not setup (not sure details, perhaps this is how encryption works). The angle on the install was that my Time Machine and Old HD were encrypted. MBP late 2011 replaced HD with SSD (Samsung 850 EVO). Thought that I would add this comment in case someone has similar situation. Use Migration Assistant to transfer apps and data from your old HD to your new HD in the iMAC. You may need to use Disk Utility to format or erase your new HD if it doesn't show up.

Now go to the App Store and Download and install Mavericks. It's just like booting when the drive was still in the iMac but maybe a little slower.Ĥ. When it boots, it should recognize your old HD in the enclosure and give you the option to boot from that drive. Hold down the option key on your keyboard and turn on your iMac. Plug in the enclosure and its USB or firewire cable to your iMac.ģ. Use the iFixit HD Replacement Guide to put your new HD into your iMac and put your old HD into the enclosure.Ģ. Didn't tell me why, it just told me it couldn't do it. When using a Recovery disk to install Mavericks, OS X just told me it couldn't install Mavericks. This Mac OS X Install Guide is really outdated.
