OS X Lion – Available for download or purchase
Sometime today (probably after 9am ET), OS X Lion will be launched and available for downloading. This is a very exciting release, although as we have mentioned in our previous post about upgrading, we strongly recommend that business users wait at least 30 days before making this transition.
Upgrading OS X Lion today
If you decide to upgrade to OS X Lion today (and ignore our advice -:)), we recommend that you do so on a non-mission-critical machine or on a separate partition of a hard drive. This way, you can begin confirmation of applications support. Here are some very important items to consider when upgrading:
System requirements for OS X Lion
- OS X Lion Requires a full 64 bit compatible Intel Processor. For example: the Core 2 Duo, i3, i5, i7 and Xeon. Some of the earliest Intel Processors are not supported (Core Solo and Core Duo).
- At least 2GB of RAM (although 4GB is preferred).
- 4GB of available hard disk space for the download and we estimate at least another 10 for the installation.
What to do prior to upgrading to OS X Lion
When we last wrote about ensuring your software was compatible with OS X Lion, the latest information we had indicated key software vendors would not have their applications ready. Let’s discuss those:
- First and foremost, your current OS X should be 10.6.8 and have all available Apple Software Updates. You cannot upgrade to OS X Lion without running 10.6.8. So, if you are running Leopard, read more about what to do.
- Rosetta is no longer available with OS X Lion – this means that PowerPC versions of your Apps will not work on OS X Lion.
- Backup! Make sure to have a current Time Machine, Carbon Copy Cloner (or SuperDuper) or whatever software you use for a local backup.
Software updates for OS X Lion
- Adobe CS2, (and most likely CS3) is not compatible.
- Adobe CS Suite 5.5 should be compatible with OS X Lion (here is the official post).
- Bento 4.0.4 is compatible.
- FileMaker Pro should be compatible (no official post).
Intuit
- QuickBooks 2011 is compatible with OS X Lion (make sure to have R10 installed). All previous versions are not.
- Quicken 2007 is not compatible.
- Quicken Essentials should be compatible.
Marketcircle
- Has a beta update available for Daylite. More information here.
- Only the Daylite client is compatible (with the beta). DO NOT UPGRADE your Daylite Server. There is an outstanding issue with OS X Lion and upgrading with break your Daylite Server.
- Billings Pro 1.5.2 client is compatible with OS X Lion. Billings Pro Server is not compatible (similar to Daylite Server). There will be a beta of Billings Pro that should provide some compatibility in the future.
- Billings 3.7.1 is compatible.
Microsoft
- Microsoft Office 2011 14.1.2 is compatible with OX Lion, although another update may be published soon.
- If you already have Office 2008 installed, it should be compatible (make sure it is current with 12.3).
- If you try to install Office 2008 after installing OS X Lion, you will not be able to do so, as the Office installer requires Rosetta to install. Thus, make sure to install Microsoft Office 2008 on your Mac prior to upgrading to OS X Lion.
- Microsoft Office 2004 is not compatible (it is a PowerPC app).
Omni Group
- All of the Omni Group apps are compatible.
There is a broader compatibility list for software apps and OS X Lion available as well. For hardware compatibility updates with OS X Lion, you’ll have to check with your manufacturer’s Web site.
Should you upgrade to OS X Lion today?
Honestly, no. This is your business and you need to take software upgrades (especially OS) seriously. We recommend holding off. More importantly, we highly recommend holding off on OS X Lion Server until there is additional information available for your server applications.
Of course, if you want to talk more about upgrading OS X Lion, please don’t hesitate to call or contact us. We are here to help guide you through the transition.
