Illustrator starts and immediately closes in snow leopard

I have recently installed trial versions of both dreamweaver and illustrator CS4 on my mac, and although dreamweaver runs flawlessly, illustrator crashes immediately every time I open it. The splash screen appears, it does its little startup song and dance, but about a second after it opens it closes again. No error message of any kind.
I've spent about four hours trying everything I can think of. Reinstalling the program does nothing. I scoured the internet for some mention of this problem, but I can't find anything quite like it.
It's driving me nuts! If anyone knows how to deal with this issue I would be very grateful.

Check, whether the default configuration and data for diocument templates, swatches etc. are in place and accessible. This should be in Library:Application Support:Adobe as well as in a similar sub-folder of your user account.

Illustrator starts and immediately closes again

Hello Adobe community,
I'm having a problem. When I click on my Adobe Illustrator CS6 to start it, it opens and immediately closes again and says "Illustrator was unexpected closed". Did you have similar problems. DO you have a solution for my problem?
I would be thankful for a reply!

Nobody can help you without proper system information.

Logic pro 8 will not close in snow leopard

I have a quad core intel mac pro and have just installed Snow loepard, now when I run logic pro 8 I can not close it down (Logic pro 8) I have to force quit every time I finnish. Does anyone know if this can be fixed? (latest version of SL and LP8)

Hey Karl,
Not a problem!
Ah, I was hoping we'd finally find that there was something common that was causing this issue! I noticed that none of the AU instruments you are using are the ones I use, so it doesn't seem that this issue is related to any of those (I only use BFD2, Melodyne and Ozone)...
I am keeping my fingers crossed that now I've unticked the "backup to MobileMe" box, it will continue to allow a proper quit over the next few days! (Sometimes things seem to be fixed and then the next day the issue returns...!)
Let me know if you do get closer to a solution. I am using Logic 9, not 8, but the issue started when I moved to Snow Leopard 10.6.1 (I'm pretty sure... it was definitely some time after getting 10.6) and I believe we are having the same problem despite different versions of Logic.
Cheers,
Mike

Why is searching so much slower in both Lion and Mountain Lion than Snow Leopard?

Hi, I use Snow Leopard run on several Mac Pros to perform multidimensional time-lapse-imaging in our lab. Snow Leopard provides instantaneous (seconds) searching for folders containing the image sequences I require for analysis (distributed across 4 x 2TB hard drives- images are saved under the structure Time\Position, and for analysis I need to retrieve all folders with the same Position label). Lion and Mountain Lion either fail to search or are painfully slow. For analysis I use internal hard drives connected as external volumes via USB and I suspect this might be part of the problem, however the same setup works flawlessly with Snow Leopard.
This problem is becoming very frustrating as I can’t figure out what has changed, or whether I am overlooking something obvious. I installed Lion on my MacBook Pro over 6 months ago which is when I discovered this problem and had to reinstall Snow Leopard. At that time I had hoped that the next OS might provide a better search function for our use, but after some testing it seems the same. To search through folders manually takes over 10 x as long as using a simple search in Snow Leopard. Can anyone provide me any advice as to what might be causing this problem and whether there might be a solution? I’ve tried a few free searching tools from the app store, but these do not perform any better than searching in Finder. I would obviously prefer to be able to invest in new Macs in the future which run the most current OS without having to install Snow Leopard on them all (if this is even possible without future models without causing compatibility problems).
Many thanks for reading and for any advice you can give me.

How do I disable Lion and go back to snow leopard

I up graded to Lion. Now my wireless router can't connect because it doesn't support Lion. I don't want to have to buy a new router.
Can I disable lion and go back to snow leopard?
P.S. I am new at computers so be easy on the terminology please.

It would help if you gave some information on WHY the router isn't working. Start with the basics:
-What brand and model is the router? If you can get a version number, that is also sometimes helpful. This info is generally printed somewhere on the router, usually a label on the back or bottom.
-What do you mean by "doesn't support" - did you get this info from the manufacturer, or is this based on you not being able to connect? Routers use standard wireless protocols (called 802.11a/b, g, or n). The network cards in Mac computers also use these same protocols.I can't think of a reason why it shouldn't work.
-Does your router have a wired connection? If so, can you connect with an Ethernet cable? You may need to be able to connect to the router directly to change settings.
-How old is your router? And have you ever tried to upgrade the firmware settings on it?
-Can you connect to ANY wireless routers anywhere else with your Lion computer?
-Do you have any OTHER computers (Windows or Mac) that can successfully connect to your wireless router?

How do I remove Lion and go back to Snow Leopard OS?

How do I remove Lion and go back to Snow Leopard?

If you have the white upgrade disk (originally, you had Leopard and bought SL later), easy. I'm not sure if you have the grey disks (you bought the machine with SL).
If you have the white disk, the first thing you do is get a USB external HD. Format it to GUID with disk utility.
Insert the white SL disk and restart. Follow the instructions to install SL on the external disk.
Have a look here for a step by step tutorial for setting up the external HD: http://www.maciverse.com/installing-snow-leopard-onto-an-external-hard-drive.htm l
From here on in you have two choices:
1. You can run SL off the external disk and keep Lion and all your files/data on the internal disk.
This is the easiset thing to do. You can open files from your Internal Lion disk by navigating through to it in Finder when you're booted in to SL on your external disk. Practical if you have a desktop machine, maybe not if you have a laptop that you need to carry everywhere (you'd have carry the external HD with you all the time).
Any non-Lion only (i.e., not Safari, Preview, Terminal and Mail Lion upgrades) apps should also run off your Lion disk when you're booted into SL, but if you have any problems, just drag them from the Lion Apps folder to the SL apps folder.
2. Move everything over to the external disk if you plan to install SL back to your internal disk.
Start copying over all your apps and files manually by dragging them from the internal disk Apps and Folders to the external disk Apps and Folders. If you have Time Machine, you can also copy your files by navigating to Time Machine through the Finder rather than trying to use the Time machine interface.
You might spend some days doing this, but it's worth doing it manually. When you're done and sure you have everything, google 'Carbon Copy Cloner'. Download it (its free), and clone your external HD to your internal HD. SL restored!

I have a MacBook Pro (15-inch, Late 2008) and am currently running Snow Leopard 10.6.8. I would like to know which is the most stable upgrade for my model. I have read some reviews of Maverick and Yosemite making the older macs slower. Is this true?

I have a MacBook Pro (15-inch, Late 2008), Intel Core 2 Duo 2.53 GHz, 4GB Memory. and am currently running Snow Leopard 10.6.8.
I would like to know which is the most stable upgrade for my model? Mountain Lion, Mavericks or Yosemite?
When I had gone to the apple care centre in India a few months ago to upgrade my OSX to Mountain Lion, I was told that considering my macbook pro's specs, upgrading it would just make it less efficient, and that I should stick to Snow Leopard unless I consider buying a newer mac that would benefit from it. Is this true? I find it a bit hard to believe. Which update is most recommended?
I also notice that my mac has gotten considerably slower. While using chrome, it buffers and struggles with even just 5 tabs open. Could this have something to do with my current ios? As a precaution, I have always been making sure I have enough free space on disk i.e around 70 - 100 free out of 250GB.
Any advice is appreciated.
Thanks in advance.

Mavericks is no longer available from the App Store, so your choice is Yosemite. One option is to create a new partition (~30- 50 GB), install the new OS, and ‘test drive’ it. If you like/don’t like it it, you can then remove the partition. Do a backup before you do anything. By doing this, if you don’t like it you won't have to go though the revert process.
Check to make sure your applications are compatible.

I am new to mac's and have upgrade from Snow Leopard to Lion but......

I am new to mac's and have upgrade from Snow Leopard to Lion but not all my application will work. Is it save to reinstall using original snow leopard dvd and does it wipe all my other application like apature? I am in a panic over this, any help!!
I came across this online and i want to know is it safe to do this:
Backup your User folders to an external drive. This should preserve your documents, photos, music, etc. If you store those things in locations not in the User folder, make sure to copy those over too.
Insert the Snow Leopard disc. Restart your Mac and hold down C to boot to your DVD drive.
Go to Utilities in the menu bar once the installer pops up and select “Disk Utility.”
Find the drive in the sidebar where Lion is installed, select it and navigate to the Partition tab.
Click on the drop down menu under Partition Layout and select “1 Partition.” Hit Apply.
Now navigate to the Erase tab and make sure “Mac OS Extended (Journaled)” is selected, then hit Erase to delete all data on the drive.
Quit Disk Utility to get back to the Snow Leopard installer and proceed with the install.
Restore your User folder and documents from your backup.
Run Software Update to get everything current, install your apps from your original install media and update those as well.
if any one can help me that would be great, thanks Mike

Before you do that why not do this first:
Repair the Hard Drive and Permissions
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
To boot from the Recovery HD restart the computer. After the chime hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
If this doesn't help, then you can proceed to reinstall Snow Leopard as follows:
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard 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 Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard. I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
This will erase the drive so be sure to backup your files before doing this.

I am ready to dump mountain lion and go back to snow leopard

Can someone stop me? I am so frustrated with lion and now mountain lion that I am actually looking at dumping the OS X 10.8 and reverting back to snow leopard.
I have a small office with three mac machines. I have been a fan of the macs for many years, even though we have software for enigineering that requires a windows versions. I have several issues that will not go away on each machine. I have a table below that describes a few of the problems. These problems have left me and my staff with no trust that our work is safe (yes, we do backups and TM). Our work flow is no longer fluid or fun with mountain lion.

I am normally a good troubleshooter and have resolved many issues so far. But they just cntiue and I am spending a lot of time resolving problems with the machine's OS that I could be using for productivity. I guess I feel like the old days as an engineer in an office where windows requires a near constant windows administrator.
Is this just me whining? Is anyone else suffering through the OS X 10.7 and 10.8 issues?
Somebady tell me I am crazy... I just want to get back to work.

Time machine and backward compatibility to Snow Leopard

Please bear with a long background explanation but I am not sure what is relevant. I have two Mac notebooks both backed up using Time machine to separate USB Hard drives. I upgraded to Lion on both machines but decided to revert to Snow Leopard on the MBAir (instability in one application that I use a lot). I backed up the MBA using time machine to the USB drive and did a second backup to the NAS. I then erased the MBA hard drive using Disk Utility and tried to reinstall Snow Leopard using the "MBA Software Reinstall Drive" (a USB flash drive). Following the instructions that came with the drive didn't work and neither did the (different) instructions in the user guide. I then tried using the Recovery drive on the MBA and Disk Utility to install SL. I did some thing wrong (but I am not sure what) and it told me I could not install SL to the same drive. Eventually I got the OS installed from the USB flash drive.
Perhaps foolishly I left the USB backup drive connected to the MBA during this process. When I had fininshed the OS installation I looked for the Backup drive and couldn't see it. I checked Disk Utility and it showed the drive but did not recognise the name of the partiton and said the partion was not mounted. It would not mount the drive and had no options to repair or verify disk. There was some other information but I did not make a note of it. I tried to read the drive on the MBP and it opened for about a mintue and I could see the files but then it disappeared from the MBA - same story. I tried to repair disk in Disk Utility but it said there was no problem with the disk.
This morning, I connected the drive to the MBP (NB running 10.7.2) again to see if I could see what the problem might be and the backup files were back and presumably accessible.
OH! I just reconnected the USB drive to the MBA (running 10.6.8) and got a message saying (the dialogue box has disappeared) something like: it could not read the disk because it was written in 10.7.2. I guess that is the explanation but where do I go from here? It is not at all helpful to do all the backups and then find they are not backward compatible.
Is there a way for me to get the MBA to access the Time machine backup via another computer? Or can I do use a different method to access the data?
NOPE. Its happened again. I just reconnected the Backup Drive to the MBP (running 10.7.2) and now I can't see the disk. Disk Utility shows the partiton as unmounted and once again it won't mount. This time there was a repair option and I clicked it and got the following error messages: "Disk Utility stopped repairing 'disk3'" (it seems to have given it this name) In the 'Details" it said
Invalid Volume Header @ 0: incorrect block type
Invalid Volume Header @ 999539297792: I/O error
disk3 is not a CoreStorage volume
Error: Storage system verify or repair failed.
I don't know if this is an OS problem or a disk problem or both. Any thoughts?

I would say disk problem.
If it were mine, I would reformat it and see if that corrects the problems.
If not, it is time to send it to recycle.

How do I remove Lion and go back to Snow Leopard?

I spent half a day downloading and installing Lion today.
All my Microsoft Office applications are now unusable. This is unacceptable!!! It is more important to be functional with my apps than to have a fancy new OS that doesn't allow me to work!!!
So, please, how do I uninstall/remove and go back to Snow Leopard?

MacIntouch Lion comments:
The Office for Mac team recently posted a blog post concerning Lion compatibility. You can find that blog post by following the link below:

How to get Lion off my computer and go back to Snow Leopard???

How do I get rid of Lion and go back to Snow Leopard PERMANENTLY?
I am not techno.
I need simple instructions with plain descriptions. I do not have any discs. The iMac came with Snow Leopard and I loaded NOTHING.
I should never have bought Lion. It is awful.
Please someone tell me how to get Lion off my computer and go back to Snow Leopard.

Can I use time machine to restart the machine before the fateful day when I bought and installed Lion?
Yes, if you have a pre-Lion backup, but you need an installation disc.
Is there anything else I can do? more RAM?
I don't know how much RAM you have. It must be at least 2 GB, or Lion wouldn't have installed. If that's all you have, you might get better performance by adding more. But from your description, I doubt that your problem is due entirely, if at all, to a lack of RAM. If you want to troubleshoot the problem, it will take some patience and effort, and you'll need to be in a calm frame of mind.

First, I'd advise you to make a backup. Time Machine is fine, but I recommend making a bootable backup with Carbon Copy Cloner if possible.
Then, insert the Snow Leopard DVD (it's a retail version, right? Not a grey disk meant for another machine?) and run the installer on the disk. Should be automatic from that point in. You don't need to reformat your drive.

I have a macbook pro and the software with snow leopard only has upgraded to 10.5.8, do I need to purchase mountain lion to upgrade to 10.6.8?

Your machine likely can't handle Mountain Lion 10.8 nor 10.7, if it does it will run slow and very higly likely a lot of your third party software and drivers for printers and scanners won't function anymore.
It's because your 10.5 era (or earlier) machine is rather dated, hardware has advanced and is faster, the newer OS X versions have gotten bloated.
I do recommend you call Apple via phone and order the 10.6.3 white retail disks, backup your personal data off the 10.5.8 Mac to a external storage drive and when the disk arrives, stick it in and run the upgrade installer.
Once that's finished, reboot and use Software Update to get to 10.6.8 and stay there. You can buy stuff from AppStore, just don't upgrade to 10.8 (or 10.7) as thats when you'll have issues.
10.6 should run your currrently installed PPC software and hardware drivers. But 10.7/10.8 will not.
10.6 is receiving security and other updates from Apple as more than 50% of OSX users are still on it.
