Xcode wont install. Upgrade to lion?
Hey!
I have a MacBook pro that is currently running Mac OS X v10.6.8 (Snow Leopard). I need to download Xcode and have found the older version of it that is supposed to work on this version from the apple dev website. I get up until the actual "install" button in the installation wizard and it says this:
"The installation failed. An unknown installation error has occurred. The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance."
When I enter the PDF file that came with the download, it tells me that this is Xcode 3.2.6 for Max OS X 10.6 and iOS 4.3. I am unsure as to why it is not installing. There is more than enough HD space.
Do I have to upgrade to 10.7.4 (Lion) before I can use Xcode?
If yes, how exactly do I go about upgading to Lion? Does it cost? How much? Will it wipe my HD?
It is imperative that that last question is correctly answered because it is not just my laptop, it is shared with someone else.
Please help me ASAP as this is a rather urgent matter.
Thanks in advance,
Daniel.
Welcome to the Apple Support Communities
I recommend you to upgrade to the most recent OS X version, so you will be able to make applications for OS X Mountain Lion and Lion, too.
The upgrade to OS X Mountain Lion costs $19.99 in the Mac App Store, so the first thing you have to do is to check if all your apps are supported > http://www.roaringapps.com
Then, open App Store and purchase Mountain Lion. While the Mountain Lion installer is downloading, you can make a Time Machine backup and/or a clone with Carbon Copy Cloner
When the Mountain Lion installer has downloaded, the installer will appear, so follow the steps to upgrade to Mountain Lion. After upgrading, open App Store and download Xcode 4 for free.
The hard disk won't be wiped because of upgrading Mac OS X, but as I said, you must make a backup of your files

Ipod touch (4 gen) wont install upgrade
I am using the most up to date itunes.

Download completes, starts installation of upgrade, get a network timed out error, all goes to ****I did
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
then tried
Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
and if I have to restore the ipod to factory I may just cry!
! tried unpluging the dock and will leave it for 15mins is that does not work I will go to the store and see about replaceing the dock and then IF I have to I will then restore it but if anyone has any ideas that are simpler please let me know! -
I am trying to install xcode on a macpro running OSX 10.6.8 . It installs, but with the error that there is no unix support. Do I have to upgrade to Lion 10.7 to do this? And if so, is this a free upgrade if I have the extended 3 yr support?
thx,
PandabigXcode 4.x cannot be installed on Snow Leopard. You need a 3.x. So if that is what you used then yes, you need to install lion. If connect.apple.com still alows registration or logins using an existing appleid then you could download the last xcode 3.2.6 for free.

Imac intel core duo (2008) crashed and wont reboot after Mountain Lion upgrade
Hi can anyone help?
Hi, my imac was loaded with Snow Leopard and I upgraded to Mountain Lion a few days ago and today when I got back from leaving it a few hours the screen went funny!!! (see pic) and it wont reboot. The same screen appears straight away when restarting. I have tried holding down the shift for safe start but it didnt work and also a nv/ram pram reset (but only heard one 'mac sound')
I have my old snow leopard disk..............somewhere!!! but I'm not sure if I can boot from them if I have just upgraded to Mountain Lion via the app store download??
I didnt do a boot disk! (yes I know) or a back up (yep again...I know!) so if anyone has any ideas on how to help :-) I'd be very grateful!!
Thanks Melanie
PS is the problem called a Kernel Panic????I'm afraid my next piece of advice you won't like. I think you need to erase the drive and reinstall Mountain Lion from scratch.
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on
the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button and set the Zero
Data option to one-pass. Click on the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless. -

Just installed a HP Color Laserjet CM2320nf MFP printer, at the same time I upgraded to Lion. It prints fine, but I cannot use the scan functions. I downloaded the most recent driver! Any help would be appreciated.
HP says that the drivers for your all in one print/scanner are downloadable from apple. For the scanner to use preview. image capture or the scan icon from the print driver queue. I don't know how old your HP is, but I know that the newer Os from apple don't support a lot of older printers. You might be able find a third party driver that could work.

I bought a MacBook Pro 13" last week with Snow Leopard pre-installed. Now I am looking to upgrade to Lion. Is there a 30 day window to do that for free? I cannot review my App Store id since I do not have a Credit Card. What to do in this case to install Lion. Please help.

2011 MacBook Pro, 64 bit i7 quad core, upgraded to Lion OSx, Bootcamp installed with Windows 7, wanting to install Windows 8 (don't ask), tried downloading/installing bootcamp 5.0.5033 (both on the mac/windows partitions (actually using a parallel to run Windows)), error message something similar to bootcamp doesn't support this Windows
So the question is am I doing something wrong? Should I just try and install windows 8 through my windows 7 partition and see if I can use the bootcamp 5.05033. Or do I solely have to use the bootcamp to install Windows 8? I'm not too familiar with bootcamp and how it runs.if you're using parallels and full bootcamp then you're making it 100% more troublesome for youself then it needs to be
bootcamp is running windows directly on the hardware this give full memory and cpu and 3d video game power
running windows in parallels is running a virtual machine where one can't run powerful games and the like but one can have it in a window and change fast between osx and windows
parallels as the only virutal machine (as far as I know) support not have the operating system as a file on the osx harddisk but can access a bootcamp parition as virtual machine but without the benefits bootcamps provides
it's a service parallels provide for those who want both to play games in normal bootcamp and sometimes use windows in a virutal machine
just install it like a normal virtual machine and you need not worry about bootcamp drivers and the likes
plus it would mean that the windows part would be a part of the timemachine bacup of osx
which it is not when it's in bootcamp -
While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?
Originally I was running Mountain Lion as an UPgrade from Lion. I created a backup in Time Machine, performed a clean install of Mountain Lion, then I proceeded to use Time Machine to restore the back up.
When thinking about the essence of a back up restore, it occurrs to me that for all I know, I may have just wated my time IF Time Machine also restores all the old unneeded files that remain from Lion after an upgrade.
Since the backup was made while running Mountain Lion as an upgrade from Lion, did restoring this backup defeat the purpose of a clean install by reinstalling old Lion files?
If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?
-ChrisHello John!
Thank you for your response which solved my problem. For other users who may stumble upon this, I'll clear up the confusion and share how I solved the problem with your help; When looking for answers to my computer problems, finding unresolved questions where person B offers a solution and person A never comes back and says "That worked, thank you.", it demonstrates a "k-thnx-bye" user mentality that leaves others with the same problem lost. Without further ado:
It is not clear what you did because the meaning of "clean install" is vague. You can erase a volume and install an OS which leaves none of its previous content intact,
This is what I did: I erased the volume leaving no previous content intact, while then installing OS X Mountain Lion.
or you can upgrade an existing OS (or reinstall the same one) which does not alter your user - installed files.
An upgrade to Mountain Lion from Lion is what I started with initially before erasing anything. This was undesirable. Since this can cause Macs to run slower (especially whereas I'm using a mid-2011 Mac Mini), my goal was to go from operating within an upgrade to Mountain Lion, to operating within an installation of Montain Lion that was not preceded by any other oprating system.
Hence a "clean install of Mountain Lion while continuing with old apps and files" is confusing.
Well put and understood. What I should have said was:
1.Erase the volume
2.Install Mountain Lion clean
3.Confirm that Mountain Lion is functioning properly
4.Proceed to use either Time Machine or Migration Assistant to Import/Migrate/Copy over only two things; My old apps (That had been stored originally in the designated Applications folder) and all files and folders originally stored in the home folder under users.
If you restore from a Time Machine backup then all modifications that occurred subsequent to that backup become erased. It renders moot any OS X upgrade performed subsequent to that backup.
That makes sense and is just as I later suspected.
If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?
Yes.
This is what I did and everything works perfectly. Thank you so much once again!

I have a 2008 macbook pro with brand new 500GB hard drive and 6GB new RAM. My old hard drive is backed up on external drive, via time machine. When the shop put in the new hard drive (there was nothing wrong with old one, it was just stuffed to the brim), they loaded snow leopard from a disk, but I haven't put anything from the old drive back on yet....I haven't even configured my mail and am just reading mail from ipad and phone these days.
Question: Should I install Lion before I restore all the old backed-up stuff, or is it important to have anything, ( like maybe preferences) already on the computer when I download Lion. I want to be selective when restoring from time machine, because my old hard drive had a lot of ancient software and junk on it that had migrated from every computer we've ever owned, and that is many, many.
So, I'm just stuck on the best way to proceed. Also, should I install the latest update for 10.6.8 before I download Lion? I see today that some new updates have become available; java, security, safari, and apple software installer.
Thanks

But I just read your next post, and it sounds like you think I should do the back-up first, or am I missing something. I think you are now recommending that:
1. First I should install Snow Leopard,
2. do the combo update of 10.6.8
3. THEN USE BACKUP to restore what I want to carry over to new drive.
4. Then upgrade to Lion.
I would restore SL and do the Combo 10.6.8 update. Then use your backup to load back in what you want. Then do the upgrade to Lion.
So what made you change your mind?
And, just to say again, the hard drive is completely new. The shop installed 10.6.8 from the installation CD, and I haven't even configured email. I'm only using safari. I just now downloaded 4 updates that software updater recommended. It now tells me it is up to date. Is there any reason to do a 10.6.8 combo updater?
Are you recommending to do the back up BEFORE I install Lion, so that there are some preferences and information about old passwords and certain information that Lion will want to know about? Will it make my life easier to back up BEFORE I install Lion?
What changed my mind was your second post. You don't want to carry over everything to the new drive and the install of Lion. You only want selective things and of course your personal files.
For that I "feel" it best to install SL, Update SL to the most current version, Then selectively restore the parts you want and then install Lion on top of that newest install of SL with the selectively restored parts on the new Hard drive.
That should give you as clean an upgrade as you can get.
Of course you could go a completely different route. Make the Lion install USB, Save all your program Install files you want to be installed in Lion along with your personal files. Then Wipe the drive and install Lion clean. Then RE-Install your programs and copy over your personal files.
That is what I would do as I do not like upgrading to a new OS over the top of an older one. I have never found that to be as clean and it always seems to carry over stuff from the older OS to the new one. But that is me. -

after the install upgrade my imac wont load anymore i tried to do a safe mode load and wehn i do at the end of it it tells me that i have a "systemShutdown false" what does this mean
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitirion & use Disk Utility from there to Repair the Disk, then Repair Permissions.
If that doesn't help Reinstall the OS. -
I have Snow Leopard 10.6.8 installed. For me to use XCode 4.5, I must have 10.7 or later. What is the best way to go ahead? Should I install OS X Lion and then move to Mountain Lion, or can I straight away install latest Mountain Lion, i.e. 10.8.2
You can directly install Mountain Lion 10.8.0 to 10.6.8, and then apply the 10.8.2 Update.
Hope this helps -
