Will my iMac 2007, 1GB RAMM be able to run OS X Lion?

Hi just wondering if i need to upgrade my RAMM to be able to run Lion on my mid 2007 20inch iMac, i've got a 2011 Macbook pro which will easily run it i know, but was just wondering if my iMac will be all right.

It will not install unless it detects at least 2 GBs of RAM is present. Just upgrade your RAM. Your machine can accommodate up to 6 GBs using 2 - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMMs.
Look for suitable RAM at DataMem or OWC.

Will my early 2008 MacBook Pro be able to run OS X Yosemite?

Will my early 2008 MacBook Pro be able to run OS X Yosemite?

I have the same Macbook Pro as you. You should read this Apple page: http://www.apple.com/osx/how-to-upgrade/?cid=wwa-us-kwg-mac-com While you can install Yosmite, many cool features will not work on pre-2012 models, including: Handoff and Instant Hotspot, AirDrop, AirPlay Mirroring, Peer-to-Peer AirPlay and Power Nap. Additionally, if you have not already upgraded your iPhoto library from iPhoto 8.1.2 (as I have not), I believe you will need to purchase the upgrade after you install Yosemite based on what I read here: https://discussions.apple.com/thread/6602872 . Good luck! If you do or have proceeded with updating to Yosemite, please come back to this thread and share how the experience went. Thanks.

Will script written in 2012 SP1 be able to run in version 11.1?

I am writing a script in 2012, but I just found out that one of my end users is only on version 11.1.
Will they be able to successfully run the script or are there too many differences between versions?
thanks.

Hi 2Pale4TX,
There's a good chance it will run in 11.1, and if you're motivated you can always adapt it to run even if it doesn't at first. The issue is mainly that there are new commands that have released between 11.1 and 2012 that 11.1 can't use. Attached are documents that list the new features for those versions.

It should run in your iMac properly

Will the iMac Intel up Convert to 64Bit when running a 64bit app?

I am running Avid Media Composer 5.5.1 (Latest Version with 64 bit) on iMac 24" Intel Core 2 Duo 3.06GHz with 512 VRAM.
I have OSX 10.6.7.
I read somewhere that OSX Snow Leopard would convert itself to 64 bit when you run a 64 bit app.
Where do I check that?
Or how do I up convert to 64 bit?
Please reply back soon
Thanks,

Never heard of that. A 32bit Application would run in 32bit mode, and a 64bit App would run as 64bit.
You can check the with the Activity Monitor (Applications -> Utilities) by looking for the entry "Kind" after the Application Name.
The system itself can be checked by
Apple menu -> About This Mac -> More Info... -> Software -> "64-bit Kernel and Extensions: No/Yes"
The iMac here works as an 32bit machine, but running Applications in 64bit.

What year, CPU speed and screen size is your iMac?
It appears as if it's one of the 2006 models that can only take up to 4 GBs of RAM, but only 3 GBs is recognized.
3-4 GBs of RAM is really the working minimum amount for OS X, alone.
The minimum iMac hardware spec for OS X 10.8 Mountain Lion is a mid 2007 model iMac.
2006 models cannot run Mountain Lion, but can run OS X 10.7 Lion.
If you have a mid 2007 or newer iMac, my advice would be to install, at least, either 6 or 8 GBs of RAM.
OS X, by itself, to run smoothly,quickly and efficiently can use between 3-4 GBs of RAM leaving virtually no RAM for any additional applications.
If you have an iMac that can take more than 8 GBs of RAM, think of installing more if you can afford it.
Purchase reliable Mac RAM from online vendors Crucial or OWC (Other World Computing) also known as macsales.
Good Luck!

I want to upgrade to Lightroom 5, but I'm concerned about compatibility with my 2008 intel Core 2 Duo iMac with only 4G of Ram. Will I be able to run Lighroom 5 if I upgrade from Snow Leopard to Lion?

I want to upgrade to Lightroom 5, but I'm concerned about compatibility with my 2008 intel Core 2 Duo iMac with only 4G of Ram. Will I be able to run Lightroom 5 okay if I upgrade from Snow Leopard to Lion? What will happen to the applications that aren't 64-bit compatible? Also the Eye-one Display 2 colorimeter to calibrate the monitor will not run on Lion, so that will be an expensive upgrade to an i1DisplayPro. Is the upgrade important enough to offset the expense? I have an Epson R2000 printer. Will there be problems with the drivers if I upgrade to Lion? It would be great to hear from other mac users who are also photographers and who print their own photos.

Before upgrading to Lion be sure to read this link:
https://discussions.apple.com/docs/DOC-6271
Adobe lists these requirements:
http://www.adobe.com/products/photoshop-lightroom/tech-specs.html
Looking at http://www.everymac.com/ even the earliest 2008 iMac was fully 64 bit, even though Boot Camp doesn't support 64 bit Windows on that machine.

Once I upgrade my iMac 10.6.8 snowleoprd to mavericks will I be able to run my Lroom3 and PsCS5.1?

Once I upgrade my iMac 10.6.8 snowleoprd to mavericks will I be able to run my Adobe Lroom3 and Ps CS5.1 with no problems?

according to this reliable compatibility chart, they should run fine in Mavericks: http://roaringapps.com/apps
you can type in "lightroom" and "PS 5.1" in the search bar to see for yourself.

I am running Snow Leopard on my iMac and have partitioned my hard drive to run Windows XP. If I upgrade to Yosemite, will I still be able to run XP?

If I install VM Fusion or Parallels, does Windows run all the time? How does that affect computer performance? and how much do I need to worry about hard drive corruption?
Current versions of Fusion and Parallels are compatible with Yosemite. Both are applications which you only run when you want to run Windows within them. As such, there's no effect on computer performance when they're not in use. Like any other software, there is some additional load on your Mac when both Windows and the Mac OS are running together, but any noticeable effect depends on what each is being expected to do and what resources (e.g. available RAM and the number of CPU cores) you can devote to each.
I think there's less chance of HD corruption with a VM than there is with running Windows natively on the Mac in Boot Camp. Consider that, with a VM, you can create Snapshots of the state of your VM at a given time, and then, if something goes wrong (virus, malware, software installations), you can simply restore the Snapshot in a matter of seconds and eliminate the problems in the process. Moreover you can make a backup copy of the entire VM file, and replace a later version if you wish. Also consider that you can assign, say, 100GB of HD space to the VM, but the actual space devoted to the VM is only what's actually used; as more is needed, more is made available and Windows can't tell the difference. So, for example, my Win 7 Pro VM has an 80 GB virtual HD but only takes up 45 GB on my SSD, and that's with XP Mode in VPC installed inside it.
Microsoft no longer supports XP, though virus signature updates are still being issued. But MS has installed a pop-up message about EOL that won't go away (it's installed with KB2934207). Even if you remove that KB in Add and Remove Software, the pop-up continues. But if you have a Snapshot or a backup which is prior to it's original installation, you can skip installing KB2934207, and suppress it's reappearance on a Software Update list.

Imac 2007 and maverick will be compatible

With all the description of maverik, I have the impreion that my imac 2007 dual core will roon better, or this will only apply to i5 up cpu. Will I have full compatibiliy will the apps? thank!

OS X Mavericks has got the same requirements as Mountain Lion. Just open System Information or System Profiler app (in /Applications/Utilities) and check your model identifier. If it's iMac7,1 or a higher number, your computer is compatible.
We don't know anything more about OS X Mavericks, so you will have to wait until the final version is released to know if your computer will work properly. Note that this version includes a huge number of performance improvements and a better memory management, apart from OpenGL 4 compatibility and more. See > http://www.apple.com/osx/preview

Using Magnetic iSight Mount ( with FW iSight ) on iMac 2007

Guess this is not a smart question...
I am able to "mount" the original Firewire iSight using the Magnetic Mount on top of the iMac 2007 ( with built-in iSight ).
So under this scenario, does the "magnetic field" from the Mount may have any side-effects over the built-in iSight circuits or other interior components?
(especially when I mount the external iSight right in the middle of the iMac that is ... on top of the built-in iSight ) Thx!

Do you feel any magnetic pull when you move the mount over the center but not touching? If not, you can't use that mount there, it will simply slide off.

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 must 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
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s MobileMe service; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
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. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
        1. iMac (Mid 2007 or newer)
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)
         3. MacBook Pro (Mid/Late 2007 or newer)
         4. MacBook Air (Late 2008 or newer)
         5. Mac mini (Early 2009 or newer)
         6. Mac Pro (Early 2008 or newer)
         7. Xserve (Early 2009)
     Are my applications compatible?
         See App Compatibility Table - RoaringApps.
     Am I eligible for the free upgrade?
         See Apple - Free OS X Mountain Lion upgrade Program.
     For a complete How-To introduction from Apple see Upgrade to OS X Mountain Lion.
Note that you need a specific 2007 model to run Mountain Lion.
