Cannot boot into macbook pro - Cannot access recovery mode I have a macbook pro 2019 with macos Mojave installed on it. It suddenly stopped working and stuck at apple logo for some unknown reason.
I tried Command + R to access recovery mode. There is no error message. It shows apple logo and fills the progress bar. I waited for more than 30 mins but nothing happened. I tried releasing the keys immediately when apple logo appeared. Also tried holding the keys until the progress bar filled.
Then I tried Command + Option + R for internet recovery. On the spinning globe screen, I connected to wifi network. After download, it gets restarted and again stuck at same apple logo. I waited for more than an hour everytime but nothing happened.
And then I created a bootable usb and tried to install Catalina OS from it. The result is same, it stuck at apple logo.
As a last option, I installed macos in an external USB using my friend macbook. I tried to boot into external USB by holding Option key on startup. Again the same result, it stuck at apple logo.
I also tried Command + Option + P + R to reset PRAM. Nothing worked. Assuming my macbook has T2 security, I cannot disable it since I'm unable to access recovery mode. Please suggest if there are any other options.
I tried Apple diagnostics by holding down the D key. After checking for few minutes, it shows no problems found.
When I try target mode by holding down the T key, it showed 2 icons, thunderbolt and usb. When I connected it to another MacBook Pro with a cable, the target MBP didn't show up in the host MBP. I did check in disk utility and network folder, not found anywhere.
I tried the verbose mode by holding down Command + V keys. The logs shows 2 messages frequently. One is &quot;X86PlatformPlugin result 0&quot; and the other one is &quot;Interface link is not up, do not pull packets yet&quot;. It keeps showing these 2 messages. Also seen &quot;kextd stall[0], (60s): 'IGPU'  &quot; and &quot;kextd stall[1], (60s): 'IGPU'  &quot;. Attached a video link of recorded log. https://youtu.be/YFo9Ja63w68
If you have access to a working Mac, the next thing I would try (after what you have already done) is to start the troubled MacBook Pro in Target Disk Mode by powering on the computer and holding down the T key until the Thunderbolt (or USB) symbol appears on the screen. Then connect it to the working Mac, mount the drive, and use Disk Utility to to verify and, if needed, repair the drive. Also take this opportunity to make a copy of the drive in case (a) the drive is failing or (b) you end up with a repair that includes a new drive. Obviously if Disk Utility cannot repair the drive, take it to Apple for service.
If the drive appears good but the computer still will not boot, the next thing I would try is running Apple Diagnostics by turning off the computer, turning it back on and holding down the D key while the computer starts up. If any issues are found, Apple Diagnostics suggests solutions and provides reference codes. Take note of those reference codes and give them to Apple when asking for service on the computer. Note that you need to be connected to the internet to run diagnostics. If D does not work (possibly because there is something wrong with your disk drive) you can use Option+D to load the diagnostics over the internet.
If the diagnostics show nothing wrong and the Target Disk Mode show nothing wrong with your drive, I would be pretty surprised. In any case, having made a backup of the drive from Target Disk Mode, if Disk Utility did not get the drive back into bootable shape, I would take the computer to Apple for repair.
