Tag Archive: MacBook Pro


Further to my earlier post https://tickett.wordpress.com/2011/03/25/virtualbox-issue-in-osx-on-new-macbook-pro-i7-2011/ it sounds like the bug is fixed in VirtualBox 4.0.7 (see http://www.virtualbox.org/ticket/8474)

However, I’m currently running my MacBook Pro with the 32bit kernel because of the issues I described here https://tickett.wordpress.com/2011/05/08/macbook-pro-2011-freeze-crash-issue/ and pre-4.0.7 works fine in the 32bit kernel.

Fingers crossed- this will fix for any of you running 64bit kernel.

*Update* I have written a script to automate the process

*Update* I recommend considering ways to avoid wasting space with your backups

This is an update on my earlier post after finding another article: http://forum.wegotserved.com/index.php/topic/18462-getting-mac-backups-to-work/

1. Configure a share on the server ensuring you have credentials for a user with read+write permission
2. Make a note of your ethernet mac address (found in network utility). Regardless of the interface you will be using for the backup this must be your ethernet mac address!

and your computer name (found in sharing)

3. From the terminal execute the following command:
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
4. From Disk Utility click new image (select custom size and enter your hard disk size in GB, replace YYY with your computer name (from above) and ZZZ with your mac address (from above, dropping the separator- e.g. C82A140BCAF2), format = mac os extended (journaled), encryption = none, partitions = single partition – apple partition map, image format = sparse bundle disk image):

5. Mount your samba share from finder (Connect To Server from the Go menu)

6. Copy the .sparsebundle file you just created from the desktop to your samba share
7. Launch Time Machine, click Select Disk and choose the samba share. The backup should start in 120s!

There is talk of a company called Orbital Technologies creating an add-in to do this automatically http://www.wegotserved.com/2011/02/21/windows-home-server-2011-support-time-machine-backups-addin/

Paul also mentioned in a comment on his article that someone is in the process of writing a script to automate the process- I’ve asked about said script and depending on the response may decide to write a script of my own.

*UPDATE* There is an update to this article here: https://tickett.wordpress.com/2011/05/10/time-machine-backup-with-windows-home-server-2011-update/

I’ve never used Time Machine before but after some recent hardware issues and the introduction of my new fileserver I felt it time to give it a try.

I read some articles suggesting WHS 2011 was going to support Time Machine out of the box- it doesn’t, damn! I found two very good articles on how to get it working:
http://www.mediasmartserver.net/2011/05/05/guide-backing-up-your-mac-to-whs-2011-with-time-machine
http://sbs.seandaniel.com/2011/02/how-to-enable-timemachine-backup-for.html

I stumbled on a few steps so thought I’d blog what worked for me (I expect this same process works for any samba fileserver and is not limited to WHS 2011):

1. Configure a share on the server ensuring you have credentials for a user with read+write permission
2. Make a note of your ethernet mac address (found in network utility)

and your computer name (found in sharing)

3. From the terminal execute the following commands (replacing XXX with your mac hard disk size in GB, YYY with your computer name (from above) and ZZZ with your mac address (from above):
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
sudo hdiutil create -size XXXg -type SPARSEBUNDLE -nospotlight -volname “Backup of YYY” -fs “Case-sensitive Journaled HFS+” -verbose ~/Desktop/YYY_ZZZ.sparsebundle
4. Mount your samba share from finder (Connect To Server from the Go menu)

5. From the terminal copy the .sparsebundle file you just created to the newly mounted share (I found trying to do this using drag & drop generated an error)- replace /Volumes/AAA with the mount point of your samba share:
sudo cp ~/Desktop/YYY_ZZZ.sparsebundle /Volumes/AAA
6. Launch Time Machine and click Select Disk, choose the samba share and the backup should start in 120s!

Recently I’ve been having a few issues with my new MacBook Pro- doh! There’s a lot of talk online linking it to overheating issues with the cpu/gpu but the suggested workarounds haven’t helped. Yesterday I booted OSX using the 32bit kernel instead of the 64bit kernel (holding the 3 & 2 keys whilst powering on the mbp) and, fingers crossed, no problems since!

I have been running some intensive apps: handbrake, vlc with external monitor connected via displayport/hdmi etc and stressing the laptop and everything seems AOK!

I’ve posted my findings in a long discussion thread on the apple forum: https://discussions.apple.com/thread/2768351?start=1290&tstart=0

Some of the ways in which the freezing / hanging / crashing has manifested itself:
-laptop refusing to wake from sleep
-coloured wheel appearing and being unable to do anything
-extremely loud beeping coming from the system speaker I think?
-panic

Keep you posted.

*Update* This is now fixed in VirtualBox 4.0.7 and above: https://tickett.wordpress.com/2011/05/17/virtualbox-issue-in-osx-on-new-macbook-pro-i7-2011-update/

Finally having got round to migrating my virtual machines over from my old MacBook Pro to find they’re running like a dog!

I messed around for ages- even tried creating a new VM but no joy!

A bit of googling turned out a bug which has only today been flagged as critical: http://www.virtualbox.org/ticket/8474

Let’s hope it’s fixed ASAP!

My New MacBook Pro

I resisted for a short while after the new MacBook Pro was released (feb 2011) but couldn’t resist when someone sent me a 15% off voucher for BestBuy. On top of this I already get 8% cashback through quidco and a further 1% through my egg credit card :)

I went for the 15″ core i7 2.2GHz (the 13″ is a bit small for some of the video/photo editing I do, but the 17″ is a little big for on the train etc). Unfortunately BestBuy don’t do the options (SSD, AntiGlare screen etc) but I ordered 8GB of ram direct from Crucial dirt cheap and a Kingston 128GB SSD from eBuyer which i’m going to put in place of the optical drive (I barely use cd/dvd these days- mostly blu-ray so i carry a slim USB external drive anyway).

I put my old 2008 MacBook Pro on eBay and dug the original receipt out- it’s dated almost exactly 3years ago (definitely the longest a computer has lasted me)- it sold for just over half the original price I paid (which went toward half of the new one :)

Anyway- so far, so good- and no doubt i’ll be blogging about the amazing performance boost I see when the SSD gets delivered.
