TenFourFox supports add-ons, but not plugins, that is, you can't use Flash at all. TenFourFox seems to be actively developed (version 17.0.3 was released Feb 16 2013). If you use a PowerPC processor you may want to try TenFourFox. OS X Leopard (10.5), or greater: 32-bit and 64-bit Intel If you use an Intel processor you can use Opera: Intel-based Mac: Opera (thanks to Cybermatatu for this one!) with older Flash 10.3 (beware, Flash 10.3 is an archived version and is no longer supported nor updated with security fixes by Adobe). If you do, then download and install it onto your computer.PowerPC-based Mac: TenFourFox and no Flash. Though it goes against Apple tradition, Apple has (thankfully) released 10.9 for free as long as you have the system requirements to run 10.8 a simple Google search will help you determine that.

You can up- grade from 10.5.8 to 10.6 by purchasing the installation DVD for $19.99 (w/ free shipping), then up- date 10.6 to 10.6.8, for free using the Apple Software Update application already installed on your iMac. So rest assured, you can upgrade all the way up to Mavericks if you so desire. If you are sure you bought it brand new in stores between 2009-2010, it was probably what Wikipedia calls the Early 2009 model.Įven if all of the previous deductions were incorrect, as long as you are 100% certain that the iMac has an aluminum housing (i.e., the outside is gray, and not white), then even in the worst-case scenario in which your iMac is from Mid 2007, you are guaranteed to be able to install OS X 9 (Mavericks). Thus, you must have what Wikipedia calls an Aluminum iMac. Since 10.6 (Snow Leopard) came out in August 2009, and since Unibody iMac was released in October 2009, it can be assumed that you don't have a Unibody iMac.

…do you mean that the iMac was bought brand new (i.e., the newest model available in stores in the 2009-2010 time frame), or did you potentially buy an older model (i.e., from 2007-2008) in the 2009-2010 time frame?īecause you have OS X 10.5.8 (Leopard) currently, and assuming that you never downgraded your OS X, you can narrow down which iMac model you have. I remember for sure that the computer was bought around 2009-2010
