Mac Freezing Despite Upgrade to Leopard, Basic Troubleshooting

Background: For the past several weeks, when I was operating off of OSX 10.4 (i have a 2007 white Macbook), my computer has begun to freeze. It does not happen during a particular application or process, but seems more at random. The gray screen does not appear, merely the "ejection" symbol flashes and my cursor starts moving sporadically across the screen - then freeze. However, if I am currently running an application, that will continue its work, and if I have an external mouse, I can plug that in and use it. I just cannot type or use the mouse pad.
I can't tell if this is a hardware problem, or if i need a keyboard replacement. I have had it looked at, and repair the disk permissions quite frequently. I thought upgrading to Leopard may help, but the cursor and keyboard froze during installation. My hard drive is filled, I only have about 4.8 Gigs of free space.
I am not a techie, but feel I have done some reading and tried to cover the basics before I post here. Any ideas will be helpful, before I see if i need to drop any $$ on a new keyboard or hard drive. Thanks.

Okay. So i went through and back up all my files and removed many. My hard drive is now almost 40% free. I have verified all the permissions as well. However, my computer/mouse/keyboard still froze on me. It only functioned for about 24 hours until the original problem occurred. I shut it down, and even upon restart it only went a couple minutes until freezing again. Thoughts? Thanks.

Bluetooth Mighty Mouse keeps freezing after upgrading to Leopard

My bluetooth mighty mouse has frequent, intermittent freezes (which appear to be a loss of sync to the iMac) after upgrading to Leopard (now 10.5.1) from 10.4.11 on my iMac 24" alum body. This mouse was rock solid on my iMac running Tiger. Luckily I do have a corded mouse which I've been forced to use the past week or so.
Can anyone suggest anything?
Thanks.

I was just trying to help my Dad with the same exact issue (Mighty Mouse stops working on waking from sleep & trying to open bluetooth prefs at that point causes the system to lock up. Have to hold down power button to reboot)
Oddly I have Leopard on my iMac 2.16 Core 2 Duo and have no issues with my Mighty Mouse.
Hopefully someone comes up with an answer .... My Dad is 80 and just bought a new Powerbook and Mighty Mouse. It's hard to explain why the mouse doesn't work.

Mac errors after upgrade to Leopard

Hi,
Just completed the upgrade to Leopard and having some problems with errors on my Mac. Tried both Disk Utility and Disk Warrior, it does not fix the issues at hand. Any suggestions or advice?

Buy new mac w/free upgrade to Leopard?

Hello,
I know this is a long shot but if I buy a new Mac now is there any possibility that Apple will do a free upgrade to Leopard when it comes out? I know that Microsoft does this with it's operating system when you buy a computer nearing the date of the new OS arrival.
Thanks,
David

David, in the past Apple has offered a reduced upgrade to a new OS when you've bought a new Mac within a short window of time prior to the announcement. For example, Tiger's release was announced 25 days after I bought my PowerBook so I wound up getting a Tiger upgrade for $20 if I remember correctly.
But there's no guarantee Apple will do that with Leopard and, of course, we don't know when Apple will announce Leopard. My standard answer is always this: If you need the computer now, buy it. Waiting is a fool's game, you can always find a reason to delay your purchase. I had a friend who kept finding a reason to wait another month and that went on for 6 years!

MacBook Pro & Mac Pro Both Upgraded to Leopard, All is OK So Far

I thought I would chime in with my experience in upgrading my MacBook Pro last night & My Mac Pro this morning. I made sure that I had 3 valid back ups of my Mac Pro data beforehand with my last back up yesterday morning. I also made sure that all my software was updated & checked for Apple updates as well. When I updated my MacBook Pro, I let the system validate the DVD and did an upgrade (not clean install or archive & install. The entire process (install DVD check & upgrade) took about 2 hours. I got the blue screen when it rebooted after teh install. Thanks to the posts I had seen on this board, I knew that I might get teh Apple BSOD for awhile . About 10 minutes later, my screen came up & I was able to access my wireless network no sweat. All my apps worked fine. This morning I upgraded my Mac Pro. Since I knew that the install DVD was good, I skipped the install DVD check. Initially it came back & said that the install would take about 1 hour and 29 minutes, but it only took about 45 minutes. This time I only got the blue screen for about 2 minutes, then my screen came up. I also installed the optional apps and the HP printer drivers on the install DVD for both my systems. The only issue I had was with my external Bose desktop speakers for my Mac Pro--they would not work, only the internal speaker was working. I rebooted, shut down & waited then brought my Mac Pro up, unplugged & replugged in the speakers but all for naught. I finally called Applecare and then after about 10 minutes on hold, the external speakers began working. I rebooted a couple of times, and it seems as though it took Leopard awhile to figure out that the speakers were there. My external Western Digital My Book USB external hard drive hung off my Mac Pro was recognized w/o a problem, and my first Time Machine back up is chugging away right now. I made sure to exclude my external hard drive from being backed up. I have successfully synched my iPhone and iPod Classic and printed to my HP 2600n printer. I feel that my apps launch and shut down more quickly under Leopard, and I really like the interface, the preview icons, and especially the dock (but then I am a sucker for eye candy). I have not yet tested Spaces. So far I am very happy with Leopard. As always, YMMV (your milage may vary). Good luck, Amy (sorry for he one long run on paragraph, but the last few times I posted in paragraphs, part of my post did not get posted.)

My only beef is with Migration Assistant. It gets to the last "minute" and just sits there.
Anyway, I'm loving 10.5 to the max !!

Will i be able to keep my files on my mac if i upgrade to leopard?

Can anyone help because the information on the internet is confusing. Should I backup before I transfer and if so, what is the best and cheapest option? Thanks everyone.

Yes. If you use the Upgrade install on Leopard your files will not be touched.
Also, if you do an Archive and Install and preserve user settings, your files will remain in place.
I would purchase an inexpensive external HD and backup everything before installing Leopard.

If I upgrade to Leopard, will it resolve the problems with my iMac?

I have one of the first intel-based iMacs that came out. I bought it in January of 2006. Is it having problems because there may be bugs in it?...since it is one of the first intel-based iMacs. Some problems that I have are: Safari freezes like crazy, iTunes freezes occasionally, Mail will sometimes shut down for no reason, iPhoto freezes, and sometimes the overall performance of the computer is slower than what it should be. I have plenty of hard drive space available, so I don't think that's the issue.
If I upgrade to Leopard will this resolve these problems? Or will it just slow my computer down even more? If that won't solve the problem, what else can I do to speed my computer up, and stop things from freezing?

Upgrading to Leopard in itself will not fix your system problems. However the act of doing a clean or Archive install of the system whether it be 10.4 or 10.5 could very well resolve your issues. So it's not necessarily the fact that you are upgrading rather doing a clean install. My recommendation would be to try and figure out your issues first then decide whether you want to upgrade or not.
How fast is your processor and how much RAM do you have? Have you installed all of Apple's software updates? A good starting point is to open up Applications/Utilities/Disk Utility select the hard drive on the left(the Mac OS X Volume) and click Repair Disk Permissions then Verify Disk. Repairing the Permissions is something that should be done often as regular maintenance and Verifying the Disk checks the volume directory for errors. If it finds any problems you will need to boot up the the install disk and run Disk Utility from there in order to Repair it. Afterwards Go to the Apple Menu/System Preferences/Startup Disk and make sure that the Mac OS X volume is selected as the startup system.

Should I upgrade Intel Core Duo 1 Mac Mini (2006) to Snow Leopard?

Okay I have a 80 GB Apple Mac Mini with Intel Core Duo 1 proccessor that shipped with Mac OS X Tiger (10.4.7) currently running 10.4.11 that I want to upgrade to either Leopard or Snow Leopard in a few months just in time for Christmas which I acquired in September 2006. It was the first Mac Mini model to include Apple's Front Row software and shipped with an Apple Remote (I know Macs don't ship with Apple Remotes anymore you have to buy them separately) and am now pondering an update. I've heard some things about Snow Leopard not working so well with older Macs even Intel based Macs that are only 32 bit.
Thing is I just got a new MacBook Pro that shipped with Snow Leopard and it seems to run fine on the MacBook Pro except for the fact a few applications I wanted to install wouldn't work with Snow Leopard like Google Desktop for Mac so was wondering if I should update the Mac Mini also to Snow Leopard. I do not particularly like how Apple removed the transcoding features to export video from one format to another in QuickTime X that was available to QuickTime 7 Pro users (actually reinstalled QuickTime 7 Pro on my new MacBook Pro so I can still use that despite QuickTime X being installed) but like Expose integrated with the Dock Menu that's new in Snow Leopard and features like Cover Flow built into the Finder (available also in Leopard along with Spaces) so if I update the Mac Mini should I update to Snow Leopard or Leopard?
This is a 2nd generation Mac Mini (the 1st generation had PowerPC chips) with Mac OS X Tiger and I've heard some negative news about upgrading Mac Mini to Snow Leopard so I want to get some more feedback on whether or not its worth it. The Mac Mini came with iLife and iWork 06 versions but updated iWork to iWork 08 Family Pack. Still have iLife 06 though and am still running iTunes 8.2.1 on the Mac Mini.
I use this computer as my main system for syncing with iPods (I have a 5th gen video iPod and a 2nd gen iPod Touch that I sync with the iTunes Library on my Mac Mini which includes videos purchased earlier from iTunes Store and music purchases as well as TV purchases) so don't want to risk messing up the system with a Snow Leopard update if it is going to cause problems doing so. If Snow Leopard is not good for the Mac Mini will just update to Leopard and stick with Mac OS 10.5 Leopard on this system.

I upgraded my mac mini 1.5GHz core solo to a Core 2 Duo 1.8Ghz in order to run most of SL's 64 bit stuff. I bought a pulled Core 2 Duo from ebay for $29 and it took about 1.5 hours to do the switch.
The main downside with the 2nd gen Mac Mini is the kernel cannot run in 64 bit mode due to a 32 bit controller that cannot be upgraded. Yet, booting into 32 bit kernel is SL's default setting and as you may have read in articles when SL came out, relying on a 32 bit kernel does not slow down use of 64 bit apps. I maxed RAM to this mac mini's 2 Gig limit years ago which is a good thing for you to do too.
I am happy to report the upgraded Mac Mini runs much faster than originally thanks to the 2 gig of RAM and the Core 2 Duo chip. Installing SL made it run faster still and consumption of memory for apps is lower (smaller pipeline requirements with faster CPU), and about 14 GIG of HDD space was recovered since I did not reinstall Xcode tools. I can now encode 1.5 hour long video files that used to take overnight processing time. CPU runs hotter, up to 89ºC, but usually run only about 10º higher on average than before while fan rev's not noticeably more than before between 1500 to 1800.
If you are not comfortable to upgrade the CPU, I think you will still find some benefit to SL for $25. Alternatively you could sell your Mac Mini on ebay (these 2nd gen model are popular for those want to do the upgrade) and use the proceeds to buy a refurbished current gen Mac Mini.

Please help - computer is crashing & freezing ever since upgrade to Leopard

Ever since upgrading to Leopard, my computer has been crashing a lot more. Sometimes it just freezes up. Most recently, I got the gray screen with a bunch of different languages telling me to restart using the power button. Here is the crash report. Can anyone tell me what's going on, and if there's anything I can do to help?
Thanks!

How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

I want to upgrade my 2007 Mac desktop to 10.5 Leopard. I am currently running on 10.4.11. When I put the leopard disk into the drive all it does is make a weird noise and then spits the disk right back out. It doesn't do this with any other discs, only this software. Is it still possible to update this computer?

Yes. Try Amazon.
Before you do upgrade to Snow Leopard, make sure your Mac meets the requirements.
Mac OS X v10.6 Snow Leopard - Technical Specifications
Make sure the disc you tried using doesn't have any fingerprints or smudges on it. The optical drive can't read the disk otherwise.
If your Mac won't read the disc, might be a good idea to rule out any problems with the startup disk BEFORE trying to upgrade the system.

I had Leopard on may Mac. I upgraded to Mountain Lion using Snow Leopard. I can't use my video with Mountain Lion. Can I load Snow Leopard on an external hard drive so I can use it with my camera?

I had Leopard on may Mac. I upgraded to Mountain Lion using Snow Leopard. I can't use my video with Mountain Lion. Can I load Snow Leopard on an external hard drive so I can use it with my camera?

First, you cannot do this if you have a Boot Camp partition.
Second: Create a new partition.
1. 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.
After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.
Third: Install Snow Leopard.
Boot from your Snow Leopard DVD. Follow instructions for installation being sure that before you actually install Snow Leopard you have selected the new partition as your target destination.
Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo
appears.
5. Wait for installer to finish loading.

I want to upgrade my Imac from tiger 10.4.11 to Mac OS 10.6 Snow Leopard. What is the best way to do this.

I have just purchased an iphone 4 and it needs me to have the latest itunes on my computer. I have not upgraded by computer for some time and thought this is probably the time to do it. My computer is an imac intel with Tiger 10.4.11. I want to upgrade my Imac from tiger 10.4.11 to Mac OS 10.6 Snow Leopard or higher. What is the best way to do this? Appreciate any help as I am out of practice. I used to be an old hand at this, but things have moved on since I didn't upgrade or use my computer as much!

The best way, really the only way, is to purchase Snow Leopard.
Online (UK): http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard
Elsewhere: call the phone number in the Apple Online Store.
Apple's price is $19.99, £14.00, €18.
Snow Leopard is not available to download from any legitimate source.
Once you install Snow Leopard, upgrade iTunes to version 10.7 or the latest, iTunes 11.
iTunes 10.6.3 is the last version of iTunes to support Mac computers with Mac OS X 10.5.8 with either Intel or PowerPC processors, but since you have an Intel iMac, the best solution is to purchase Snow Leopard. Leopard is no longer available from Apple and prices from aftermarket vendors can be unreasonably high.

10.4 Tiger Unlimited - Upgrade to - Mac OS X 10.5 Leopard 10-Client License

Can I just upgrade my current 10.4 Tiger Server Unlimited to Mac OS X 10.5 Leopard Server 10-Client License?
I have many email lists, and websites on m current server, but I only have six clients that are named.
What would I have to watch out for?
The only modifications were to change SpamAssasin so that the settings could be easily upgraded.
Is there something that could return my 10.4 server to it's standard state, and then, just upgrade?
Could I just reinstall 10.4, then upgrade all the 10.4 steps to 10.4.10, then upgrade to 10.5?

+There are two aspects here. Technical and License. If you have only 6 concurrent file sharing users, then the 10-client license will work fine.+
I have only six concurrent users. I was just concerned about upgrading from one to the other.
+Not knowing what modifications you may have made it is hard to tell. Personally I prefer to setup servers from scratch between major version changes.+
I am sorry. The only modification was to shift from ClamAV to FreshClam.
+What services are you running on your server?+

Easiest way to upgrade from Apple Mac OS X 10.5, Leopard to Mountain Lion or Lion without buying Snow Leopard?

I have a 2009 Macbook Pro with Apple Mac OS X 10.5, Leopard on it and I'm starting to get annoyed with the fact that some stuff is not compatible with this OSX anymore. I would like to be able to upgrade to Mountain Lion or Lion but without having to fork out £15 on Snow Leopard when it won't get used, or should I upgrade to Snow Leopard and not bother about upgrading to Lion or Mountain Lion.
Thanks in advance
Matt

You have to get Snow Leopard first.
Start by checking if you can run Snow Leopard:
Requirements for OS X 10.6 'Snow Leopard'
http://support.apple.com/kb/SP575
The OS 10.6 Snow Leopard install DVD is available for $19.99 from the Apple Store:
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
and in the UK:
http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard
but nobody knows for how long it will be available.
When you have installed it, run Software Update to download and install the latest updates for Snow Leopard.
To use iCloud you have to upgrade at least to Lion, but some functions are only available in Mountain Lion:
http://support.apple.com/kb/HT4759
You can also purchase the code to use to download Lion (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:

(NB: PowerPC applications can still be run in Snow Leopard using Rosetta, but they will not work in later versions of OS X. For detailed information see this user tip: https://discussions.apple.com/docs/DOC-6271 )
The OS 10.6 Snow Leopard install DVD is still available for $19.99 from the Apple Store:

and in the UK:

Before installation you should back up all your data.
When you have installed it, run Software Update to download and install the latest updates for Snow Leopard to bring it up to 10.6.8, or download the combo update from here:
http://support.apple.com/kb/DL1399
Check via Software Update whether any further updates are required, particularly to iTunes (you will need the latest version in order to synch with mobile devices).
You should now see the App Store icon in iTunes, and you now need to set up your account:
