Laptop instantly reboots when trying to install?
3 3

Question

I'm trying to install Mac OS X Mavericks on my Acer Aspire V7-482PG but when I press enter to install I can see the Apple logo for a split second and the laptop just reboots ..

I tried to start with -v but i'm not very experienced so I don't know what most of it means:

Same problem here, i have tied nocpu=1, xpcm-free, -v, -x but so far... No luck.

 

Installing from USB, it is a Haswell CPU 16gb ram with H87 cipset. (Board by Gigabyte)

You're my hero! It worked using xpcm-free.

Too bad it doesn't work for you though :/

What I tried is booting with -v and recording the screen with my phone and pause it so I could read the log that flashes by, maybe some important info could be found there..Edit: Have you tried all of these?http://www.macbreaker.com/2012/01/list-of-common-hackintosh-boot-flags_29.html

Nice nice nice!

 

xpcm-free

That does the trick for me on its's own.

Viva la revolution!
 

- I should be more specific.

Intel Haswell laptop. Tried loads of flags, but nothing worked until I tried the xpcm-free flag. Other flags may be required for you!

Good luck :)

xpcm-free works when you want install Mavericks in your PC. But after installing, you can enter inside os x maverick and no problem until you update your mavericks with a combo update.

 

When I updated mavericks 10.9.0 to 10.9.4 (with 10.9.5 passed the same) with a combo updated downloaded in the Apple official site, I can not enter inside mavericks again. Instant reboot appears again (and xpcm-free don't work this time, a message says that this command don't exist).

 

Any suggestion? Thanks
