Apple macbook pro 2011 wont boot up6/3/2023 ![]() I haven't noticed any video problems (except for when I was changing out the memory: I got a couple of strange all-blue screens, but that could just be a result of poorly seated memory). Reboot the computer again to see if the Mac stuck on Apple logo issue exists. Step 3: Select the system drive from the sidebar. Step 2: Select Disk Utility from the macOS Utilities menu. ![]() Hold Command + Option + P + R keys while booting Mac to reset NVRAM. Step 1: Boot your Mac to macOS Recovery mode: hold down Command + R keys immediately after pressing the power button to turn on your Mac, release the keys until you see the Apple logo. Wait a few seconds and press the Power button to turn on Mac. The symptoms don't exactly match what is listed there. Press and hold the Power button for a few minutes till Mac turns off. On a side note that might be more relevant than I think, I noticed that this model is one of the models potentially implicated in the MacBook solder scandal (see which lists the 15" Early 2011 model as one of the model lines with problems). Before I make that definitive conclusion, I'm wondering if there are any other ideas that I might try? P.S. then it must be the motherboard that is bad. Replaced internal memory: symptoms unchangedĪttempted boot with charger unplugged: symptoms unchanged Question: Removed Hard Drive completely (and attempted to boot from USB memory): symptoms unchanged After another reboot returns to original behavior.īoot from USB memory (with MacOS Sierra install): boot menu appears, and allows me to select the USB memory stick for booting, after starting boot process from memory, returns to original behavior (note that I used same memory stick to load MacOS Sierra onto a Mac Mini with no problems) Screen flashes momentarily, then grey screen appears.Ĭlear NVRAM: Apple logo and loading bar appears, freezes, and stays that way forever. If no lights are on, the battery is completely drained and the MacBook Pro wont start up unless the power adapter is connected.Loading bar loads part way, freezes for a while.I have a MacBook Pro 15" (Early 2011) model which suddenly is not booting correctly.
