![]() ![]() I have downloaded TransMac to create a bootable USB to try recover off as I currently do not have any other working macs to create a recovery usb on my windows pc. Only extra thing I have done is reset the pram as one site suggested that and that has not helped, if anything made things worse as now it seems much slower. I haven’t been able to find anything specific on that error code or what to do about it, just the usual stuff my friend followed on the support forums. I entered recovery and checking the disk utility logs in recovery mode you can see about 30 repeated attempts all with the same text and the error 478. He then gave it to me to see if I can help him. After factory resetting it and entering recovery mode (cmd+R) he followed the steps on the apple support community to delete the old install and reinstall by deleting the partition using disk utility but it failed saying “ MacOS “Installation Failed, An Error Occurred While Installing”. ![]() Last week a friend of mine decided to factory reset his laptop as he doesn’t use it anymore and wanted to sell it. It gets all the way through than gives “ MacOS “Installation Failed, An Error Occurred While Installing”. I need some assistance in troubleshooting a A1708 who doesn’t want to re install macOS through internet recovery. ![]()
