Issue will be back if I put an SD card inside and then take it out.
#Reinstall macbook sd card reader driver update
I shall receive my Macbook back next week and I will update here on what they did change and If issue went away. Now they find out there is a hardware error and they are fixing the parts. Since now I figure out it is returning back when I use a SD Card, I returned it back to repair again this Monday and told them to try putting an SD Card. I am not sure if your issue is also related to SD Card slot usage, but it could indicate some hardware parts inside your Macbook is faulty. Issue went away temporarily but returned back as soon as I used SD Card slot.

They did a SMC reset, NVRAM reset and a full OS clean install and they told me my Macbook Pro is flawless! I had sent my Macbook to repair on 26 December, got it back on 3rd Jan. but in reality, you just skipped filevault boot login screen and went directly to OS. If you disable FileVault, after waiting long for your slow pre-boot laptop to show apple logo, it directly access the real OS, and since in real OS, issue goes away, you will see that boot is fast again. I am not sure why it is fast inside of OS, but before OS loads up, it is painfully slow with keyboard and mouse lagging. It is a fake screen that look like a real OS, but it is just a pre-boot screen.

once password is entered, Real boot process start and OS load up. It ask you for password before it can unlock your hard disk. Reason you see FileVault is slow, is because this login page is a pre-boot screen. Hold D when Macbook is turning on, you will see Diagnosis page is also slow (my Diagnosis page sometimes pass 100%, sometimes show SD Card error code). Hold Alt to go to boot device selector while booting, you will see it is slow. Problem is "EVERYTHING" before OS load up is slow. FileVault just expose this problem to you.
Guys, this issue is nothing to do with FileVault. I've had this problem since December 2016 on my 3 month old Macbook Pro 13inch Early 2015. Sorry to bring it to you this way, but it is a Hardware error and it is very hard to prove it to Apple Care at this moment because as you said, laptop APPEARS to work fine if you disable FileVault. But it was for no avail, the problem persists. Using macbook Pro retina 2015 with macOS Sierra.ĮDIT: I did a clean install (completely formatted and partitioned the HD using a bootable USB stick with macOS Sierra on it).

I was almost sending the mac for hardware repair, but seems like there may be some problem with the SD Card reader drivers? I need to do some more testing, but meanwhile, has someone experienced this, or can give me some insight on how to debug this issue? Meanwhile, I was also experience SD Card problems - they wouldn't read at all or appear in Disk Utility I now found out that if I do procedure B1 the SD Card reader seems not to work, but if I do procedure B2 it works ok. they work for 2 seconds, then they stop working for 10, then the cycle repeats itself) ī1 - move the cursor to the "restart" button and press it, or force a shutdown - start by pressing the physical button, I get the os restarted in no time, and everything seems fine BUT if I restart the os, I return to "A" ī2 - patiently try to type my password and enter the os, the mac starts normal So far, restarting or shutdown / starting the OS no longer hangs the Filevault pre-boot screen.Īfter upgrading to El Capitan, and then to Sierra, I found a strange behaviour:Ī - if I restart the os, it takes more time than usual, then I get into the boot screen with the input devices (keyboard, trackpad) responding from time to time (i.e. I had not have time to send the laptop to repair, as others did (and it fixed the issue for them). EDIT: It seems that upgrading to macOS 10.12.4 solved this issue.
