Hello,
This special tool from Apple is used to recover data from Macbook A1706. I've been using it for a while but it stops working. When connecting Thunderbolt 3 between the tool and working Macbook, Macbook should prompt "new device detected, allow or not"... but it doesn't.
Has anyone ever experience this ? It's not a cabling or power supply issue, some IC have stopped working but not sure which one. Probably the one that manager thunderbolt 3
Thanks

I got this Apple MacBook Pro A2289 EMC 3456, it was working 100% fine. I started it's updates. I am assuming that, it was writting to the SPI Bios. There after the updates, it re-booted & then no display at all. Am I doing something wrong? Are there any Bin files for this notebook & is it written the same way as older MacBooks? The amp meter shows that it taking it's 20v but amp is aorunf 0.40 ~ 0.70. If some can help & give me some information, I would be grateful. Thanks in advance. -

Thank you very much in advanced

Hi there,
I'm looking for anyone who might have information on Apple's embedded Apple Watch charging daughterboard, ID 820-02601. This is currently used by Anker in their Apple Watch charging products, but likely by other Apple partner brands as well.
You can see the board referenced in ChargerLab's teardown of the Anker Y1811 3-in-1 MagSafe cube - they discuss the "Apple Watch wireless charging circuit" about 2/3rds down the page. It's not pictured, but the board ID reads 820-02601-A, which sure sounds like Apple.

Hi Dear Friend., I am working on a Apple MacBook Pro A2338 820-02773-A. The history was that the AON Rail on the Trackpad connector JT400 was burnt. After I removed the burnt connector, I tested with the meter & no shorts. Connected the USB C power & all booted fine, no problems at all. I soldered a New TP connector put in the old trackpad with a brand new Flex cable. The laptop beeped in the start but no display. I removed the connector & the display was fine again. USED a known good Trackpad & a Flex cable, even with this still the same problem. I checked the connector whether...
