What is highest OSX for 2.7 Ghz Intel core i5

I have an iMac, 2.7 Ghz Intel core i5 that is running OSX 10.6.8. Is this the most recent OSX that this system will run, I know that there are more recent versions but the software upgrade returns that the system is up to date.

Using new battery on old 2.16 GHz Intel Core Duo

I am in a remote location, under a deadling. My 2.16 GHz Intel Core Duo MacBook Pro battery cable finally went south. I'm in a studio with half a dozen brand new battery units ... for 2.66 GHz Intel Core i7 MacBook Pro's.
Can I use the battery from a 2.66 GHz Intel Core i7 MacBook Pro on my older 2.16 GHz Intel Core Duo???
All ears,
Ben

As I wrote above, there is no possibility of using one of the new batteries in your old machine: it absolutely won't fit. Furthermore, removing the battery from one of the new machines will void the warranty on that machine, so even if you could contrive a wiring harness to connect one of the new batteries externally to your MBP, there would be good reason not to do it.
And if you did, there is no way to predict how the charging system in your machine would respond to the incorrect battery. Would it be charged at all? Would it be charged only to the capacity of the battery specified for use in your computer, which is far lower than the capacity of the new battery? Would the SMC in your machine recognize the battery and distribute the power from it correctly? The answers to these and many other related questions are anybody's guess.
So the solution to your immediate problem will be to move your work onto one of the newer computers, finish it up by the deadline, and order a new battery for your own computer.

I am using os x 10.4.11 on a 2.4 ghz intel core 2 duo. I don't believe I can install lion on this system but was wondering what is the highest version I can use?

Here are the requirements for Lion:
http://osxdaily.com/2011/06/07/mac-os-x-10-7-lion-system-requirements/
In order to install Lion you have to have Snow Leopard and then update to 10.6.8:

Personally I suggest that you stop at Snow Leopard. It still is the most efficient OS that Apple has devised and it still works great. Go to the Lions only if there are feature that you really need. There may be a price to pay in slower performance though.
Ciao.

Mac OSX for the 13-inch Early 2011 Thunderbolt 2.3 GHz Intel Core i5 model.

I got a refurb MacBook Pro two days ago.
It is the 13-inch Early 2011 Thunderbolt 2.3 GHz Intel Core i5 model.
It came from Apple with Mac OSX 10.7.1 Lion installed on it (and no media on disks).
According to EveryMac.com this model originally shipped with Mac OSX 10.6.6
The "Whats in the box" lists the software on DVD as one of the parts that should have been included but there was no disk with the MacBook.
Was there or wasn't there an actual software install media disk for this model ??
The fan runs at about 2000 rpm all the time.
Is this normal ??
Mike

10.7 Lion doesn't have disks, but a Recovery Partition accessible by holding command and r keys upon booting.
You need a internet connection, fast, strong and relaible to download Lion from Apple servers.
Since that machine came with Snow Leopard originally, you can call Apple with your serial number (AppleMenu > About this Mac > More info) and request new copies of the 10.6.x grey disks.
You can learn more about Lion by visiting these links

What version of osx would give an Imac 24'' 2.3 ghz intel core 2 Duo, with 4gb of DDR2 SDRAM, the best performance? To do illustration and design jobs.

What version of osx would give an Imac 24'' 2.3 ghz intel core 2 Duo, with 4gb of DDR2 SDRAM, the best performance? To do illustration and design jobs.
Would the more recents os versions increase the overall performance? Is it worth it?

Hello!
Snow Leopard is what i am currently using. But i guess it does need some clean up and maybe a clean install to see if it gets faster.
I believe 4gb is the limit for this model, although i've seen some with 6gb…
Thank you for the help

I tried adding more ram but the Mac would't even boot with 2x2GB installed. I figured that it was limited so I forgot about it. Wha's the advantage of adding it if it is not recognized?
Chances are you either did not install or correctly or added the incorrect RAM.

What is a recommended decompression software for a non-Lion compatible MacBook Pro 1,1 2 GHz Intel Core Duo running OS X Version 10.6.8?

My thanks to you and all other respondents. In backing up "theVault" App I thought that my ancient version of Stuffit was inadequate to unzip the backup file. I attempted to download the latest Zipit version which only works with Lion. After upgrading to Stuffit 9 I realized that theVault backup file was encrypted so as to not open on the backup Mac. One must restore to the iPhone where is does open.
My apologies for the imprecise post. I am finding limitations with not being able to install Lion on my early MacBook Pro. I can recommend theVault to those looking for a password App with secure backup.

Upgrade path for iMac 2.4 Ghz Intel Core 2 Duo from OSX 10.5.8 to mountain lion

Hi,
I have an Apple iMac 2.4 Ghz Intel Core 2 Duo with 4 Gbytes of 667 MHz DDR2 SDRAM.
It is currently running MAC OSX 10.5.8 --
I would like to know the proper upgrade path to the most current version of OSX which is
compatible with this hardware.
Thanks!

The starting point is to call Apple at 1-800-MY-APPLE and ask to purchase a copy of Mac OS 10.6 "Snow Leopard." It will cost about US$20 plus shipping. When you receive it, install it and use Software update to get to OS10.6.8; the updates are free to that point.
Now you will have the App Store app in your Dock. You can use that to purchase Mac OS 10.8 "Mountain Lion," the lastest. According to the MacTracker database, your iMac--which is either a Mid-2007 or Early 2008--can support 10.8.
CAVEATS:
• your iMac is at or near the minimum level to suport 10.8; performance may not be stellar
• if you currently run any old PowerPC apps (like Office 2004), they will still work unders 10.6 but no higher. You will have to upgrade to newer versions to continue using them. Office 2008 runs on either PPC or the newer Intel Macs. Office 2011 runs only on Intel Macs.

I have an early 2008 macbook pro that is running slow after upgrading to lion. Is there anything I can do? this is what I have,Processor 2.4 GHz Intel Core 2 Duo, Memory 2 GB 667 MHz DDR2 SDRAM.

First, back up all data immediately, as your boot drive may be failing.
Launch the usual set of applications you use when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. What approximate values are shown for Reads in/sec and Writes out/sec?
Step 2
You must be logged in as an administrator to carry out this step.
Launch the Console application in the same way as above. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Post the 50 or so most recent messages in the log — the text, please, not a screenshot.
Important: Some personal information, such as your name, may appear in the log. Edit it out before posting.

Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Get an external hard drive on which to store some of your files after which you can
      erase the data from your internal drive to free up space.
5. Also see Freeing space on your Mac OS X startup disk.
6. See Where did my Disk Space go?.
7. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

If I close the computer and open it back up, it sometimes stops for a little while, then will spontaneously start again. Any help would be truly appreciated. Thanks!

See this knowledge base article. Also, you might want to update to 10.6.8 (don't know that that will fix your problem, but it's the latest version of Snow Leopard).

24" iMac 2.8 GHz Intel Core 2 Duo OSX v10.5.5 shutdown anomaly

24” iMac 2.8 GHz Intel Core 2 Duo OSX v10.5.5 shutdown anomaly.
I have noticed that when my iMac shuts down, that initially the One Touch Maxtor 500G external drive attached to the Firewire 400 port also does a normal shut down and the light goes out. Within a few minutes I noticed that the light on the Maxtor is back on. This does not happen if I use the USB 2.0 port to attach the hard drive and iMac, the light remains off. It appears the FW400 port is active on the iMac even when in the shutdown mode. Is this normal for the iMac?
I have a 13”MacBook 2.4Ghz that does not activate the same Maxtor when it is shut down. I attach it via the MacBook FW400 port.
I hooked up an ammeter to the iMac power cord and observed the following readings:
iMac Off: From 50ma to 180ma cycling at a rate of 23 cycles/minute. Using the Watt reading of the instrument, that amounted to cycling from 0 to 5 Watts every 4 seconds.
iMac On: 1.16A 133Watts.
This iMac is new, 1 week old, does it need repair or is this normal? I like to get a FW800 external HD, but I don’t want to have to pull the plug on the HD every time I want to shut down.

Since my Maxtor doesn’t have an on/off switch, the best solution I have found so far is to use my APC 750 UPS to turn off the Maxtor. This APC has a master plug outlet that senses when the computer is turned on and activates 3 other outlets to on when the computer reaches a certain power threshold. Fortunately the threshold is user adjustable and I was able to set it high enough to turn off the Maxtor outlet when the iMac is off.
Is anyone else able to confirm that their iMac cycles like mine does, or is this peculiar to my iMac? It is new and if it needs service I would prefer to do it while it is covered under warranty.

Hello, I have a Macbook Pro 17'' 2.4 GHz Intel Core i7 (2011). I dont know what happened but the pixels on black or dark areas on my monitor are displayed in a flickering red color, and on white areas are light blue. Any idea??

Hello,
I have a Macbook Pro 17'', 2.4 GHz Intel Core i7 (late 2011). I dont know what happened but the screen shows red flickering pixels everywhere where it should be black, and light blue pixels where it should be gray, I had this problem twice, the first time it just disappeared by itself. Now it's been like this for days, I have really no clue.
Anyone with the same problem or solution?
This is how it looks like:
Thanx

Is that a camera picture or a screen-shot? Is there any difference? i.e., can you capture the problems in a screen shot, or not?

Is it possible to upgrade a macbook 2.16 ghz intel core 2 duo to OSX 10.8.5?

I have an old mackbook, approx 2007 era. Is it possible to upgrade a macbook 2.16 ghz intel core 2 duo to OSX 10.8.5?

You can only upgrade to 10.7 Lion. Lion is still available from Apple. You will have to call Apple Customer Care 1-800-692-7753 or 1-800-676-2775. to purchase it. Then within 3 days you will get an email with a code which you can use to download Lion from the App Store. Or go to http://store.apple.com/us/product/D6106Z/A/os-x-lion and purchase it there. The price is $19.99.
You will have to be at 10.6.8 first.
The 10.6 Snow Leopard DVD is in the Apple online store. You can get it for $19.99. After you’ve installed that then use the 10.6.8 combo updater to finish it off. http://support.apple.com/kb/DL1399 You will need to be running 10.6.8 to access the App Store to order Lion. http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
System Requirements for 10.6:
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.
Lion will require at least 2gb of RAM but really needs 4gb to run smoothly.
As for third party 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 in 2006 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.
You can put two 2gb RAM sticks in your model 2,1 but it can only use 3,3gb. This is a hardware limitation and cannot be changed.
http://en.wikipedia.org/wiki/3_GB_barrier
http://www.everymac.com/systems/apple/macbook_pro/faq/macbook-pro-core-2-duo-3-g b-memory-limitation-details.html
OWC tests have found that there is a slight speed increase with having two 2gb sticks in rather than one 1gb and one 2gb. Your model is in the gray lines at the bottom of the graph. http://eshop.macsales.com/shop/Memory_Benchmark/Apple_MacBook/

Open the Mac App Store and try downloading Yosemite. If you get told it's incompatible, choose About this Mac from the Apple menu, check if the computer has at least a Xeon or Core 2 Duo(not Core Duo) CPU and 2GB of RAM, and if it does, click here and order a download code for Lion 10.7.
Back up your data and check your applications for compatibility before upgrading. In particular, Mac OS X 10.7 and newer don't support PowerPC programs such as versions of Microsoft Office prior to 2008.
