![]() ![]() I then proceeded to begin the revive and watched that lovely status bar flow along left to right. "Oh Goody" I thought thinking that my woes were behind me and that all would be smooth sailing from there. So, with the help of YouTube University I put it into DFU mode and sure enough it worked and came up right away on the host mac as being in DFU mode. Sure enough it came right up in recovery mode on configurator. boy was I wrong! I installed Configurator on the host Macbook Pro (2020 13") and connected the computers via a USB C cable. So here I am all happy thinking that we will just revive it and reinstall the os and be off down the road. I was like "oh good we have another mac that can do that!". I looked it up and found that you can "revive" it with another mac. ![]() I went to sleep and when I got up in the morning went to use it and it was entirely unresponsive. So I tried repairing the disc from disc utility and reinstalling the os from disc utility and it was good for a day so I figured it was all fixed. ![]() It would crash and then I was having a difficult time getting it to power on again. Well I just updated it again and it came back with a vengeance. ![]() It would do this continually and then I was able to update it again and it got better. My Macbook Pro A1990 was having issues after updating (I think it was in November) it a while back, it would crash and then I could turn it on again. Macbook Pro T2 2018 15" A1990 Bricked After Update - Won't Turn On Hey guys I need help. My Mac knowledge is not great but if anyone has some step-by-step advice, I’d be really grateful as I’m getting nowhere. I’ve also tried rebooting in safe mode but it gets no further than the grey screen and apple logo. I have re-run the verify disc option from the installation disc which always reports no problems and I’ve re-installed Snow Leopard but always the same result, the spinning beachball and a force restart. I can’t force quit, I can’t use anything, the only option is to force shutdown. Depending on how quickly I fill in this info, either during or soon after, the ‘spinning beachball’ appears and that’s as far as I can get. The Mac now starts up and does its little animated Welcome movie then requests a few registration details. My intention was to immediately update it to the latest OS (presumably Sierra again). So I dug out the only OS discs I have, Snow Leopard and after verifying, repairing and eventually, erasing the hard disc, I clean installed Snow Leopard (via an external disc as the internal CD-drive hasn’t worked for years). After reading a couple of forums, I was able to restart it and reinstall Sierra which it did up to around 95% complete, then stopped. It was running Mac OS Sierra which was as far as it would update but a couple of weeks ago, it crashed and wouldn’t reboot. I have an old 17” MacBook Pro, 3.06GHz, Intel Core 2 Duo, 4Gb Memory, 1067 MHz, DDR3, purchased September 2009. Any help is appreciated.Īlso sorry for the mistekes if i had any, cause i only know English B1 so far. I just want to know can i get it back working normally without my blood boiling because it's not working fine. Right now it runs MacOS X 10.8 Mountain Lion (i'm sure it had to be named Cougar tho) from a 64GB usb drive, because the seller i got it from didn't gave me the DVD drive and the HDD. Other than that, the computer can still work, although i have to try various keyboard combinations to clear the SMC, NVRAM, etc, just to get it boot up normally. The only things i know since then are that i have probably corrupted the EFI ROM. The beep lasted about 2-3 seconds and the machine gave no other signs of life, other than spinning up the CPU cooling fan. Hello there, this is the first time i ask a question here.ĥ days ago i was performing an Ubuntu installation on an USB drive, because i'm still waiting for my HDD and DVD cables, but i just got tired of waiting and decided toforce shut down the computer by holding the power button.Īfter it had shut down i tried to power it back on and i was greeted with one terrible beep instead of the Mac's chime. ![]()
