T440p un perfect installation of Mavericks

[RehabMan]

The recent activities:
1. create recovery partition
2. extract dsdt/ssdt from Ubunto 14 Live CD ( in ubuntu, I clicked the bluetooth application )

Now, can't recognized bluetooth any more. Would you give me some cues?

BTW: When It worked, I can see bluetooth information at USB section. Now It disappeared.


Help me SOS!

It is likely you are lacking Bluetooth firmware uploading software on the OS X side. Your Bluetooth status probably depends on whether you restarted into OS X from another OS or whether you did a cold boot....

Then, what can I do to fix it? Sorry for my starter question.

First you need to verify that is the issue. Boot Windows or Linux with full BT support, then restart and see if i t is working in OS X. If so, do research to find if there is a BT firmware uploader for your BT hardware.

Booted in Ubuntu, the bluetooth doesn't work. Maybe Ubuntu updated wrong firemware, right? Are there hackintosh tools for BT correct it?

BTW: I have no windows, I have only Ubuntu Live CD USB. or are there other linux is more suitable than ubuntu?

Thanks Rehabman!! I solved bluetooth issue! Just as what you said, I fix bluetooth issue in Ubuntu, then restart in Mac, BT works well!!

This give me a lesson. Though, I can't understand the mechanism deeply. It's works now anyway.

I've got all ssdt/dsdt from ubuntu and dissembled them in source. But I can't find GFX0 device in any file. What matter with it?

Upload all your files. Some Lenovo laptops use VID.

Files are corrupt (DSDT has invalid checksum):

Loading Acpi table from file       DSDT - Length 00071682 (011802)
ACPI BIOS Warning (bug): Incorrect checksum in table [DSDT] - 0x4B, should be 0x9C (20140828/tbprint-308)

Re-extract from /sys/firmware/acpi/tables and /sys/firmware/acpi/tables/dynamic.

I loaded the binary files from ubuntu. I can't convert it to source due not familiar with command line.
