QuickBooks 2009 Mac OS x Lion

This is a question everyone is asking. For any mac OS upgrade, the first thing you have to ask yourself is this: Did Apple create a system update that requires me to buy a new computer? They do that every now and then. If so, then you have to decide if you want to buy a new computer, and if so, if you want to commit to the Apple ecosystem, because this will happen again.

In this case, the new OS version does not require new hardware, but, iOS 9 and El Capitan are both needed on your various devices to get all the cool interoperability that most Apple users live for. For this to happen, you may need a new iPhone or iPad because the Apple mobile OS’s do not tolerate old hardware very well at all. So upgrading to El Capitan may require a significant investment of cash even if the OS itself is free.

Performance Changes and compatibility

According to one site, “OS X El Capitan is compatible with many Apple computers, including some that are as old as 2007, but many users will see the best performance gains on slightly newer hardware. That is a bit ambiguous. According to Apple, opening apps will be close to 140% faster than for Yosemite, and switching between apps is faster. So that indicates a performance improvement rather than downgrade.

Overall, according to Apple, system level graphics rendering is to be 40% faster, or better.

Apparently El Capitan fixes some problems people were having with WiFi in Yosemite. Other Yosemite bugs are fixed as well.

We look forward to Apple’s eventual adoption of a more Linux like model, where bug fixes and such are pushed out every week rather than with major upgrades.

The new OS is said to be compatible with these hardware:

iMac (Mid 2007 or newer)
MacBook Air (Late 2008 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
Mac mini (Early 2009 or newer)
