[SOLVED] Is Refit required for single-boot Arch on Macbook Pro?
I have a Macbook Pro 7.1, and now that the issue with a non-supported chipset has a workaround I am planning to create a single boot Arch system using the latest Archboot that comes with the 2.6.35 kernel.
If I understand well I need the non-efi grub combined with the firmware's bios compatibility mode if I want 2d/3d accelerated gfx, since that does not work currently with grub2-efi. One question I cannot find an answer to though is whether or not I need Refit and an EFI partition for this. The Arch wiki (nor the Debian/Gentoo/Refit docs) is not very clear about this. Is it only needed for multi-boot setups or for all setups that use bios compatibility?

Do you mean that I need to install Arch besides the existing OSX and 'bless' that arch partition from OSX in order to be able to remove all non-Arch partitions?
Veovis Muad'dib wrote:, and then make sure to never zap the PRAM..
Not that I was planning to do this, but does this remove the possibility to boot Arch?
Veovis Muad'dib wrote:As for if you can change BIOS settings, no. You can change boot disk, but that's it. What would you need to do in the BIOS anyway?.
I just thought it might come in handy for tweaking powermanagement, wake-on-lan, bluetooth and stuff like that.

Thanks all for the info!

[SOLVED] Two Grub boot menus on Macbook pro 7.1 efi boot
Hello
This is my first Arch post and I feel a bit of a fool for making the error I'm going to describe but here we go....
A couple of weeks ago I installed Arch as dual boot on my Macbook pro 7.1 and I'm generally quite happy with the result. I boot as EFI using Grub2 having followed instructions to make a standalone boot.efi and boot from the mac's bootloader. The boot.efi file is placed on a small macosx journaled partition that has been made bootable with "bless". I've been able to boot between the two systems using 'alt' at startup or, more generally, just leave the pc to boot into Arch.
When I generated the boot.cfg file I didn't specify ro or rw but grub added ro. So I've had the "root mounted as ro" warning since upgrading to 3.10.3-1 (I don't subscribe to the testing repository) although it was obviously an issue from the start and I was aware of it. After reading some of the forum posts today I thought I'd have a go at changing the boot parameters at startup and edit the boot menu to include rw. This worked and I didn't get the read only warning. I decided to try to generate a new grub.fcg and specify rw before generating a new boot.efi. On inspecting the new boot.cfg I noticed it had both ro and rw entries. I decided to think about what to do (thinking of removing the ro) before making the standalone file.
Anyway, I had to boot into osx for something else but when doing so noticed that I now have 3 efi boot options in the mac bootmanager. Two are grub and one boots osx. I've had a look in the forums and on the internet in general but can't find out how to remove the second entry. My guess is I've installed grub on my Arch /boot partition but can't figure out how to remove it.
Although I can boot into Arch as normal as the pc defaults to the original grub menu, I'd like to remove the additional entry if possible and would be grateful for any help.

Last edited by youngdm (2013-08-06 21:00:37)These are the instructions I followed
grub-mkconfig -o boot/grub/grub.cfg grub-mkstandalone -o boot.efi -d usr/lib/grub/x86_64-efi -O x86_64-efi -C xz boot/grub/grub.cfg
Then in osx:
sudo bless --device /dev/disk0s4 --setBoot
I think that on initial installation I ran the command above as one and then last night ran it as two. Like this:
grub-mkconfig -o boot/grub/grub.cfg
grub-mkstandalone -o boot.efi -d usr/lib/grub/x86_64-efi -O x86_64-efi -C xz boot/grub/grub.cfg
The instructions were from:
http://codylittlewood.com/arch-linux-on … tallation/
From the apple discussion forums..
This one is a bit more tricky, surely there is another way but this one is simple and not so risky
1- burn a GParted Live CD iso
2- boot on the GParted live CD (press alt on boot and wait for the CD boot option to appear) and choose the first boot entry
3- during the boot process accept every option with its default value
4- in GParted select the EFI partition and somewhere in the menus select the "flags" entry and uncheck "boot"
5- exit GParted Live CD and boot in Mac OS
6- a new volume has appeared "/volumes/efi"
in the finder go to "/volumes/efi/EFI" and delete the "ubuntu" folder
7- repeat steps 2/3 and step 4 but check "boot" instead of unchecking it
8- exit GParted live CD and reboot
I have found the instructions above on the apple discussion forums but as noted above I'm a little wary about following them. I guess though that I need to remove the entry in the mac EFI partition which is hidden in osx but shows as sda1 in Arch.
Do you think I could mount sda1 in Arch and have a look at what's on there? From the instructions above it looks like there should be a directory for Arch that could be deleted. I presume that Arch is booting from the blessed partition on sda4. Is this correct?

Can a Mac Pro boot off a MacBook Pro in Target Disk Mode?
Summary: "Are you able to boot a Mac Pro off of a Mac Book Pro in Target Disk Mode?" OR "Will a Mac Pro boot off an OS X install that was made on a MBP?"
Details:
I'm finishing a music project that was created on a PPC G5 Quad computer and going to a studio in Santa Monica to complete the final mixdown. My 3rd party software plug-in configuration is unique, and the studio doesn't have all of the software instruments that I do on their 8 core mac pro. My G5 software installation is mirrored to my MacBook Pro, but the MBP doesn't have enough CPU power to play the project back.
Is it feasible to have the studio's 8 core Mac Pro boot from my MacBook Pros hard drive? Essentially, we'd be using my OS and software on their powerful CPU / hardware. I figure, since they are both Intel builds of OSX, this should be do-able.
I don't have access to the Mac Pro until I show up to start working.
Thanks for any input / suggestions!The MacBook Pro boots fine in 10.5.8, and loads the Logic project without any faults. The only issue is that a CPU shortage occurs when you attempt to play the sequence.
Like you suggested, I performed separate UB installations of all the needed software on the MBP solely so I could move Logic projects from one computer to the next without a hitch. (Actually, DropBox does this for me). Migration assistant was not employed in this process due to the PPC / Intel issues you noted.
I didn't need to mention the G5 as it appears to have caused some confusion based on Kappy's reply, but I did want to explain my work flow thoroughly.
It sounds like booting the MacPro from my MBP is feasible. I'll mark this topic 'solved' and head over to the studio tonight. I'll post here any anomalies from the session (if any).
THANKS~! -
When I boot up my macbook pro, it takes forever to start and I got grey screen...Help Please.
Just a minute ago I tried to boot up my macbook pro...normally the grey screen pops up with the whirring wheel, and then my Lion log-in screen comes up and all is well. This time, however, the whirring wheel spun forever on the grey apple screen. Then the wheel stopped and it went to a solid grey screen with apple...and nothing for about 10-15 seconds. Eventually it came up. BTW, this was the 2nd time I tried to boot because the first time, the grey screen with the whirring wheel stayed up for several minutes so I rebooted.
Anyone know what might be wrong?

for the 2013 versions of macbook pro should I purchase 32 bit windows or 64 bit version to be able to install it on macbook and use windows with bootcamp?
Then you might check at any of the other university book stores or software stores or any computer store in town for the 64-bit version.
If you want to use the 32-bit version from the school (you probably get it for free or very cheap) then you could purchase Parallels and run it as a virtual machine concurrently with OS X. There are some caveats:
1. You have to purchase Parallels (there may be an academic discount.) List is $79.95.
2. Your computer needs minimally 4 GBs of RAM, but realistically 8 GBs would be better.
3. Parallels creates a pseudo-drive on your hard drive. It could easily require 50 GBs of disk space.
Accommodating these might be more costly than buying 64-bit Windows 7. And, if you look online you may find them with an academic discount (or may be able to order it through the school.) -
I'm looking for screws for the bottom of my macbook pro unibody.
I need screws for the bottom of my macbook pro unibody. They started falling out after I upgraded my RAM, apparently they had some type of threadlock on them. Apple was of little help and directed me to a an apple store or service center which is not convienent. So far, I've been only able to find the 'old' pack of 5 screws, not the pack of 10 that my mac requires. I did find one seller on ebay advertising them but would like to avoid that path if possible. Any help in this matter will be greatly appreaciated. Thanks
No this is not a common problem. Have you had the bottom off before?
The factory set screws you see a bit if blue lock tight which makes it more difficult the first time out.
They can replace the screws over the counter at any authorized repair service or Genius bar:

I have purchased the VGA Connectors for both a iMac and Macbook Pro so that i can connect my promethean board projector to the computer and I can not get the image on the screen. Does anyone have any suggestions?
Irelandbound wrote:
thank you, I have the adaptors so glad that would work. I just heard adaptors burn out often. So Just thought for my main iMac computer, a plug would be best. I will get one once I move.
Any other suggestions or things I should know about apple products in Ireland. I know there are no Apple stores there.
An adaptor doesn't burn out. It merely serves as a means to connect the power prongs on your device to the power supply.
I believe you are thinking of a transformer, which you do not need. A transformer converts one voltage to another.
You don't need to do that as the power supply of modern electronics can take almost any worldwide voltage.
Look at the label on the device. It should indicate the input power acceptable of 100-240 VAC, 50-60 Hz.
Additionally, I found the adapters cheaper in the UK than I found them in the US. They were available in most supermarket chains. I wasn't in Ireland, so I can't say one way or the other.
If you have something that doesn't have that input power spec, it would require a transformer.
On other items like electric clocks or things with motors, you can connect them up to a transformer and the voltage will be correct, but the frequency may not. For clocks, that will cause them to not keep time well. For motors, they will burn out. -
Ok, so i bought a 16GB DDR3 1333MHz RAM for my late 2011 13" MacBook Pro whose memory runs at 1067 MHz (I was also told that late 2011 MBPs run at 1333MHz, is mine an exception, if so, why?)... Im looking for all possibilities to close the compatibility gap because computer freezes at boot and was wondering if there was anything i could do to get this 16GB DDR3 1333MHz RAM to work at 1067MHz or somehow get my computer to run at 1333MHz?...
You don't have a late 2011 MB Pro.
You have a 2010 version. Your MB doesn't support 16GB. 8GB Max.
That's what it shows on your about this MAC.
You need to return the RAM and get 8GB ( 2 X 4GB ) 1066MHz.
Your system bus is set to 1066MHz.
You're having issues because you've installed more RAM than your MB can support. It's only reading 4GB per bank which totals to 8GB and not 16GB. -
i have 3 different itunes accounts and would like to combine them into just one for all my devices, a macbook pro, an iphone 4S, an older IPOD, and a ver sion one Ipad. how can i do this on all devices ?
i had one for a long time, then when i got the ipad i didn't realize they would all still work under one so i set up the second one on that
then when i got the new iphone i put in the info for the first and main one from my mac pro and it would not work at all, and i knew it was right, then it asked me to create a new one or i couldnt finish the setup
hence why i have 3 now
hard to believe you cannot combine into one
oh well, i will just make them all accessible for all 3

Where can I buy a larger hard drive for my late 2008, 15" macbook pro? From reviewing questions and answers on the support community it would appear that having Apple remove the old and install the new hard drive is recommended. But how/where?
Welcome to Apple Support Communities
You can install the new hard disk yourself if you want to. You just need a 2'5" SATA II hard drive, which is compatible with your MacBook Pro. You can buy one at OWC > http://eshop.macsales.com/shop/hard-drives/2.5-Notebook/ You can filter hard drives by computer, so press a "Click to view all...", choose your computer in the sidebar and it will give you the compatible hard drives.
There are different brands for the MacBook Pro. The most recommended are HGST and Seagate, which have good reputation. A 7200 rpm hard drive will give you extra performance -
Where can I buy a genuine apple replacement battery (A1309) for my Mid 2010 17" Macbook Pro?
Where can I buy a genuine apple replacement battery (A1309) for my Mid 2010 17" Macbook Pro? There are used batteries on ebay that don't appear genuine. There are some third-party knock offs. The apple store seems to believe they can replace it, but I have to make a reservation at the silly Genius Bar just to have them tell me how much it's gonna cost, not to mention then likely wait for them to order the battery and install it. I'm perfectly capable of installing it myself. I just need to know where I can order it?
Thanks,
AndrewYeah, that's what I've finally decided. I was kidna super frustrated because the first apple store I called wouldn't even tell me a price or tell me if they could replace the battery without a Genius Bar appointment, and as I would have to take off work and drive acros town--and I don't have a car so I'd have to borrow one--that was pretty annoying. That call left me pricing linux laptops. I called another store to see if I'd have better luck, and the initial answer was the same, but the girl relented under some trying-to-be-nice-but-clearly-annoyed pressure, and she gave me the answers I needed: yes, they should have the battery in stock and it should be a same-day replacement that should cost $179.
It just *****, really, because there's so much about Apple that I used to love, and I'm watching it kinda melt away under their success in the mobile market. As a professional user, there's less and less reason to stick with them. Instead of being the best they can be, I feel like they're just trying to be flashier and just a little better than the other mediocre computer companies. Ugh. Anyway, now I'm ranting.

Please help. I can boot up my macbook pro and log in but after that all i see is the wallpaper, toolbar and the dock. In the dock it has 2 ? where the doc and download folders should be. If I open up a new finder window it doesnt show anything in there no hard drive or anything. If anyone konws how to help let me know please and thank you.
Agree with baltwo, though even if you have saved the install app I wouldn't use it unless its been used to install a known good copy of the OS already.
In your case, that probably means start fresh:
Restart the computer, holding down 'command' and 'r'. When the recovery disk window shows, choose 'Reinstall Mac OS X'.
