Should I upgrade to Lion from 10.6.8 to improve stability of Java program i am running?

I have a Java program problem, it's unstable and losing connection and freezing. Will an upgrade to Lion from 10.6.8 help?
thanks

they don't claim it but it is. I have never had a problem with the 2008 macbook, just the desktop. Narrowed it down to this after trying everything else speaking with Scottrade, Oracle and Apple.
I tried to downgrade but got lost at the utilitoes terminal part. any easier way? Apple wont help me downgrade through my care program and I have no idea.
Thanks

Should i upgrade to lion from leopard (10.5.8)

Besides the basics, I really don't have much knowledge on using Macbook Pro.
Lately I've run across some issues with my macbook pro. Being that my 3 year apple care is expired and not renewable. I have been contemplating upgrading to Lion. If I do this, any thoughts to how much it cost? and would I have to upgrade to snow leopard prior to doing so?
thank you for your thoughts

The software cost is $29.00 for Snow Leopard then either $30.00 for Lion or $20.00 for Mountain Lion. But there may be additional costs in order to meet hardware requirements.
Snow Leopard General requirements
Mac computer with an Intel processor
1GB of memory
5GB of available disk space
DVD drive for installation
Some features require a compatible Internet service provider; fees may apply.
Some features require Apple’s MobileMe service; fees and terms apply.
Lion System Requirements
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
Some features require an Apple ID; terms apply.
Apple - OS X Mountain Lion - Read the technical specifications.
Macs that can be upgraded to OS X Mountain Lion
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
MacBook Air (Late 2008 or newer)
Mac mini (Early 2009 or newer)
Mac Pro (Early 2008 or newer)
Xserve (Early 2009)
If your computer can run Mountain Lion then you only need to start with Snow Leopard from which you can go directly to Mountain Lion.
If you need to purchase Snow Leopard you can still purchase a copy from Apple's online store's telesales agents.[1-800-MY-APPLE (1-800-692-7753) or Customer Service and Sales Support at 1-800-676-2775.] Ask for a Sales Representative.
Third-party sources for Snow Leopard are:
Snow Leopard from Amazon.com
Snow Leopard from eBay
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store.

If I upgrade to Lion from Leopard will I need to reinstall all my programs?

I have a bunch of photo & video editing software as well as some other things such as parallels on installed on my computer. I really don't want to have to reinstall everything all over again. I've tried to search this question, but I'm having one of those "technically challenging" days. For some reason, I can find everything about Lion except this.... I'd really love to upgrade, but if I need to reinstall everything, I don't have time to do right now.
Thanks so much!

You can upgrade from 10.5 to 10.6 with no problems. Any program that runs under 10.5 should run under 10.6. See this list for compatibility with 10.6: http://snowleopard.wikidot.com/ You might have to upgrade some drivers for printers, etc.... And you will have to install Rosetta if you have any Power PC applications http://www.macobserver.com/tmo/article/snow_leopard_installing_rosetta/
To upgrade your iLife and iWork. If you only want iPhoto or other single apps from iLife '11 you can get them from the App Store after you've upgraded to 10.6.6. iPhoto, iMovie or Garage Band for $15 each and Pages, Keynote or Numbers from iWork '09 for $20 each.
You can order a Snow Leopard 10.6 install disk for $29 as long as you have at least 1gb of RAM and 5gb of free space on your hard drive. http://store.apple.com/us/product/MC573Z/A?mco=MTY3ODQ5OTY
Once you are at 10.6.8 you can buy Lion for $29 from the App Store if you have at least a model 2,1 MacBook. Lion will require at least 2gb of RAM but really needs 4gb to run smoothly As for programs see this list for compatibility with 10.7 http://roaringapps.com/apps:table Also Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Lion.
Before Mac switched to Intel processors they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.

I've just upgraded to "Lion" from "Snow Leopard" which to my surprise does not support "Appleworks" I've used Appleworks for a number of years for all correspondence etc. and need to continue using this software. Do I need to go back to Snow Leopard? d

I've just upgraded to Lion from Snow Leopard and to my surprise it does not support my 'Appleworks' application software. Ihave used Appleworks for all correspondence for six years and need to refer to the files (letters etc.) from time to time. Is my only option to revert back to Snow Leopard?

The reason appleworks no longer runs is because it is a powerpc based application. Since it's end-of-life in 2007, it was never converted to intel architecture, since it was dropped as a supported product. It continued to run on intel machines via rosetta, but OS X Lion formally discontinues all support for powerpc based programs. Powerpc based applications can only be run on OS X 10.6.8 or earlier releases (ones that still support rosetta).
So, it does sound like your best option is to move to iWorks' Pages now - otherwise you will be stuck with an increasingly more outdated operating system. And if you should buy a new machine, it would not run the older versions of OS X anyway, so at some point you have to leave appleworks behind and move on. Seems best to do it now, before Pages perhaps also moves forward to a point where it too may no longer support ancient file formats.

Why can't I upgraded to lion from snow leopard

You will need to provide more information. Your question is too vague to answer.

Can I upgrade to Lion from OS X 10.5.8 (Leopard)? Do I need to install Snow Leopard first? If so, Which version?

Can I upgrade to Lion from OS X 10.5.8 (Leopard)? Do I need to install Snow Leopard first? If so, Which version?

There are only two versions of Snow Leopard, the ordinary one and the server edition. Most people have no need of the server edition. Any Snow Leopard retail disc, no matter how old, even 10.6.0, can be updated to 10.6.8, so the version is pretty much irrelevant. You need to make sure your hardware is up to scratch for Lion though - you have to have an Intel processor, Core 2 Duo or better - NOT Core Duo.

Can you upgrade to Lion from 10.6.6?

Hi, I was just wondering if it's possible to upgrade to Lion from OS X 10.6.6, or if you have to be on 10.6.8. Thanks!

If you have the Mac App Store, it is possible. But it is HIGHLY recommended that you run Software Update before installing Lion, to make sure you have the newest software - this is also required if you want iWork and iTunes to run in full screen in Lion.

The 2006 and 2007 Mac Pros can be upgraded as far as Lion. Mountain Lion can be installed on Mac Pros from 2008 onward. See below:
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard — Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space

You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion.

Should I upgrade to Maveriks from 10.6.8 or go to Mt Lion instead?

I've heard that upgrading to Maveriks can cause a lot of problems for an older MAC like mine. My model meets all the requirements for the upgrade, but I have read a lot of horror stories about Maveriks and am concerned with messing up my computer.   Should I just upgrade to Mt Lion instead?
And if so, is there a free download? Someone told me it costs $20 but I know Maveriks is free.....   thx

The Mountain Lion upgrade is not free. Mavericks is free. If your computer can survive Mountain Lion then it can survive Mavericks. But if it's too old for even Mountain Lion then stick with Snow Leopard.
Upgrading from Snow Leopard to Lion or Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8, Lion, or Mountain Lion installed. Purchase and download Mavericks (Free) from the App Store. Sign in using your Apple ID. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

Upgrade - Mountain Lion from Snow Leopard

I have upgraded my iMac to Mountain Lion from Snow Leopard. I have a MacBook Pro running Snow Leopard; do I need to purchase this upgrade again, or will the previous purchase hold good for my Macbook Pro?

On your Macbook Pro, assuming it is running Snow Leopard 10.6.8, you can log into the Mac App Store with the EXACT same Apple ID that you previously used to purchase Mountain Lion for the iMac. In the Store go to your Account's "Purchased Items" list and you should see Mountain Lion listed. Download it from there for Free onto your Macbook Pro.
Hope this helps

I want to upgrade to Lion from version 10.4.11 how do I do this?

Hi
I want to upgrade my Macbook to the latest Lion software but do I have to upgrade to Snow Leopard first then go to Lion?
Can I do this online or do I need to go in store?
current version 10.4.11
thanks

You can upgrade from 10.4 to 10.6 with no problems. Any program that runs under 10.4 should run under10.6. See this list for compatibility with 10.6: http://snowleopard.wikidot.com/ You might have to upgrade some drivers for printers, etc.... And you will have to install Rosetta if you have any third party Power PC applications http://www.macobserver.com/tmo/article/snow_leopard_installing_rosetta/ I recently upgraded an older MacBook (model 1,1) straight from 10.4 to 10.6.

I can't upgrade to Lion from Snow Leopard

Hi,
I'm trying to upgrade an older MacBookPro to Lion from Snow Leopard. The MBP was built in 2007, and has a 2.4Ghz Core 2 Duo, with 4GB of RAM. It's currently running OS X 10.6.8, which means the computer should be able to run Lion.
I have purchased Lion before for other machines, and so if I log into the App Store on this MBP, and then click on the "Purchases" tab, I see OS X Lion at the bottom of my list of App Store purchases, with an active "Download" button next to it. If I then click on "Download", the App Store puts up a spinning logo for a few seconds (up by the nagivation links in the top bar of the App Store), and then the spinner disappears, the "Download" button goes from greyed-out to active, and then that's it. No indication that Lion has started downloading or anything like that. I'm stumped. By all indications, I should be able to download Lion, and not only does it not download, but it gives me no information as to why it didn't.
Help!?!

Wait...I may be an idiot...
I went through this whole rigamarole of downloading the "Install OS X Lion" app onto a second mac, then copying that App over to the "Applications" folder of the old mac I'm trying to update. Then, when I looked in the "Applications" folder of the old Mac, sitting there right next to "Install OS X Lion" was an App called "Install OS X Mavericks". I have no memory of downloading that particular app, but perhaps it did, and perhaps once it did, the system prevented me from downloading the Lion installer...which would make some sense.
As of this moment, I am upgrading the machine to Mavericks, which seems like a win all around.

Should I upgrade to Lion? Have Mac Pro, 2.66Ghz, Core i7, 4GB memory, S-Leopard, purchased 11-2010.

Reading alot of comments on problems running Office 2011, Adobe CS5, Parallels etc. My system operates flawlessly - I'd like to migrate to LION but don't want to create a mess. I've certainly read alot of applause for Lion but haven't seen anyone list the above software as part of their install. I'd expect there are quite a few users running the same software - just need some testimonial to build my confidence that this is the right move. Any comments will be greatly appreciated.
Thanks!

Which raises the question of why would you want to upgrade? Lion is largely cosmetic, and a lot of those cosmetic differences are not pretty
- removal of coloured icons in finder sidebar, making navigation more difficult
- no scroll bar arrows making navigation more difficult (essential if you need fine control of scrollling to move around in design progs like Illustrator/ Quark),
- autosave and versions, making everything more difficult through hideous beach balling on large photoimage files in preview or keynote if you make multiple and rapid minor changes
- dodgy compatibility with some versions of photoshop
- less control over where to keep your folder (apps have to be assiged to the app folder)
- less control over what information remains on your hard disk hidden from you (including versions of your personal files).
- if you use magic trackpad on your MP, you also loose the 4-finger swipe 'app switcher' gesture
On top of all these 'features' you get given:
- mission control, which is less configurable than spaces
- launchpad, which is effectively the same as having 'stacks' and 'grid' options set on your app folder in the dock, only lunchpad takes over your whole screen and is harder to navigate.
Now, that's all IMHO opinion, of course. As someone further up in this thread advised, whatever you do use Carbon Copy Cloner or SuperDuper to clone your current installation. If all is to your liking, you can always use that disk as a regular backup drive. If all is not, the way back to your flawless system is just a five-minute reboot away.
