The process will appear to stop after the flashdrive is erased and the High Sierra Installer begins installation, but give it time (about 15 minutes). The procedure for transferring the Installer file to the flashdrive is described here:Ĭreate a bootable installer for macOS - Apple Support The flashdrive I was using also had to be formatted as Mac OS Extended (Journaled). Type this command in Terminal to format the SSD in Mac OS Extended (Journaled): Disk Utility would not give me the option of formatting in Mac OS Extended (Journaled), so that had to be done using Terminal: It was formatted as APFS, and everything I read seemed to indicate that it needed to be formatted as Mac OS Extended (Journaled). Here are some other problems that had to be overcome. ![]() I never could figure out where the Installer file went it wasn’t in Downloads. Obviously I didn’t want to install it on that computer anyway. I downloaded it on another 13 inch MBP that runs Mojave, and after the download was complete there was a message that High Sierra was too old for this computer and will not be installed. The first step is to get a High Sierra Installer through the App Store. It was necessary to use Terminal to make it work. In the end the only way I was able to get around the “recovery server could not be contacted” issue was to install a bootable version of High Sierra on a flashdrive, then boot the 2010 MBP holding down the Option key to get the installation started. Like many others, I ran into the dreaded “The recovery server could not be contacted” message when trying to do a restore of Mac OS High Sierra for a 2010 13 inch MBP that I was selling (yes I know it’s worth almost nothing, but someone wanted to buy it from me).Ĭheck Internet / WiFi connection: They are fineĬheck date to make sure it is current: It’s fineĬheck to see if Apple’s OS Update Server is up: It’s fine Hopefully this helps you guys it took me forever to get this to work!

So far this is the only way I have been able to get this to work. Step ten select the thumb drive that has High Sierra operating system installed on it and go through the installation process. Step ten close the terminal app, connect the usb stick you made to this Mac, and then restart the Mac while holding the option key. This will set the date and time on this Mac. Step eight go to utilities at the top of the screen and open the terminal app Step seven make sure the this Mac is not connected to the internet via wifi Step six On the old Mac start the Mac while pressing command option and R The second time the process finally completed. This process takes some time to complete and failed the first time I tried it so try again. DMG file you downloaded earlier and tell it to install it on the thumb drive Step five run the High Sierra patcher program and point it to the. ![]() Step four connect a blank thumbdrive to your Mac to install the High Sierra OS to needs to be over 16gigs Step Three on the current Mac you will have to allow the patcher app to install for use through the security settings Step two you will need to download the High Sierra Patcher tool Step one you will need to download a copy of the high Sierra dmg file. ![]() Ok I had this same problem and I finally got High Sierra to install.
