Thread: 10.6.6 to 10.6.8 Acer TravelMate 7520

Hi guys,

First of all thank you for reading. I got an old acer travelmate laptop currently running osx 10.6. I tried to upgrade to 10.6.8. After this. Nothing is working anymore. I do get into the system. Some items are not working. I hope someone can help me out with this.

System Spec:
AMD Athlon 64 X2 dual-core mobile technology TK-53
ATI M690G Chipset
ATI Radeon X1250 integrated 3D graphics with up to 896 MB of HyperMemory
17" WXGA+ TFT LCD, 1440 x 900 pixel resolution

Gigabit Ethernet, supporting ASF (Alert Standard Format) 2.0, Wake-on-LAN ready

What did i do.
- OSX MOD-cd
- install retail mac os
- currently running on 10.6
- Wireles card works
- Sound works
- Videocard works at 1024x768

Tried to get to 10.6.8
- install 10.6.8 combo update.
- Run legacy_kernel-10.8.0.v2.pkg

10.6.8 installation goes well and is at 10.6.8 but.
- No videocard higher then 1024 * 768
- Sound working perfectly
- No wireless card
- No LAN

Thank you very much in advance

After updating run , repair disk permissions ( Disk utility ).

Does that solve the problem with the video, audio and the wireless problems ?

Edit tried this. Still stuck on the same scenario as described above

Hmm so many view and so replies. Guess my laptop is way to old to get it up and running
