Hello RehabMan,

I am working on my ACPI DSDT. I am getting this error while trying to compile:

12773, 6126, syntax error, unexpected PARSEOP_NAMESEG, expecting '('
12796, 6126, syntax error, unexpected PARSEOP_STORE

Attached are the files I get from following the guide. Yet I am not sure is the refs.txt is giving me a true result.

Please let me know what am I doing wrong or need to fix.

Thanks.

There are no errors in the DSDT.dsl you attached.
Make sure you're using the correct tools and ACPI 6.1 as per post #1.

I did everything as the guide says, but I see in MaciASL Preferences 4.0, 5.0A, 5.1. I don't see 6.1. You mention ACPI 6.1, that is not in the guide, are you referring to iASL 6.1?

How can I update to 6.1?

This is the output in Terminal for the folder:

Robs-MBProjects robperez$ ls
iasl iasl.git
Robs-MBProjects robperez$ which iasl
/usr/bin/iasl
Robs-MBProjects robperez$ iasl -v

You are not using the tools (MaciASL) linked by post #1.
Read it carefully.

I am trying to find the GFX0 SSDT in order to patch it (so that the backlight patch can work), but I can't seem to find it in any of the disassembled SSDTs with MaciASL.

You were right! I downloaded an older version of MaciASL. Got it done and working.. Now on to the sleep/shutdown/backlight. any suggestions are welcome.

Thank kindly RehabMan.

Is this a Probook/EliteBook/Zbook?
The fix is already in the beta branch of the ProBook guide...

You should explain fully, with "Problem Reporting" files, and... in a separate thread.

I already attached the necessary files for Problem Reporting to my post. You're telling me to fix my profile, but I don't see any problem. The ioreg file name says MacBook Pro, but that's misleading since I had already changed the SMBIOS so that my laptop shows in "About this Mac" as a MacBook Air with a unique serial.

Before posting here, I had already applied the 3 changes that are part of the Probook backlight fix linked in the FAQ, but it didn't work. I came to this thread because the backlight fix thread told me I might need to patch SSDTs as well. I would appreciate it if you could look at the files I attached in my first post and help me figure out what's preventing the backlight patch from working.
