There's quite a few threads on here for removing activation lock on T2 MacBooks.
If it's been fairly recently updated to a recent BridgeOS, you may be out of luck.
There are paid services to bypass the activation lock. -

Hi everyone!
I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.
I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...06-27-2025, 08:54 AM -
Hello everyone, I have a MacBook Pro 13” 2020 (Four ports) (Model A2251 with the 820-01949-A logicboard). It had some minor liquid damage but I carefully cleaned the logic board with alcohol and let it dry as needed. Now I encounter following situation: The MacBook does start but the Battery is not charging when a cable is plugged in any of the ports (I use the powerbrick and cable that came with the device). It had some charge left, so I could safe some data, but I was limited my the 13% and the speed of airdrop. The liquid-damage is almost only limited to the side of the logic board where... -
Hi Dear friend., I am working MacBook Pro A2251 Logic board 820-01949-A. The history was that there was slight liquid on the LHS CD3217 & was not powering on at all. No 20v or any amps. I replaced with known good CD3217s & then got the power but its stuck on 5V .18amp. I did power measurements which are below:
PPBUS_G3H=12v
PP3V3_G3H=3.3v
PP3V3_UPC_X_LDO=3.3v
PPDCIN_G3H=5v ????
PP1V8_SLPS2R=1.8v
Do you think the other RHS CD3217 have to be replaced to as they might have gone defective???? -

Hello forum,
I'm still relatively new to the world of electrical repairs.
I have a Macbook here that I can't figure out
When the battery is gone, the USB input consumption goes up to 20 V and 0.06A. But it breaks down after about 2-3 seconds and you can also hear a small ticking on the logic board. But I can't pinpoint it exactly.
I removed the logic board and took a few measurements.
But I can't really figure it out.
At first I thought the infamous CD chip was defective - but then of course you read more on the internet...09-07-2025, 11:35 AM
