I'd like to increase it but wonder whether I could just add a 2GB chip or whether both chips have to be the same capacity. MacFixIt reader Michael asks: I have a not-very-new iMac with 1GB of memory. Question: Adding RAM to an older iMac system Usually this is only determined when Apple stops releasing security updates for one OS when those for newer versions are made available. So far Apple hasn't given any indication of when Snow Leopard support will be halted.

MacFixIt reader Mat asks: Will Apple still maintain us Snow Leopard folks? It doesn't seem that long ago that I had to upgrade to SL. Question: Longevity of Snow Leopard support After doing this you can connect the Mac to another one with the Thunderbolt cable to mount its drive on the second Mac. If holding the T key at startup does not load Thunderbolt Target Disk Mode, then go to the Startup Disk system preferences and click the button to restart in Target Disk Mode. Target Disk Mode can be activated directly over Thunderbolt for systems that have Thunderbolt connections.

MacFixIt reader Walter asks: Can I put my iMac and MacBook Pro in native Target mode connecting them with Thunderbolt cable, with no need for any adapter?
Question: Target Disk Mode via Thunderbolt Some examples of this are Firefox and Safari, which have both modes to allow compatibility with various browser plug-ins and add-ons that might still require the main program to be running in 32-bit mode (separate from the system kernel).
You can check for and enable this by getting information on the program (select it and press Command-I) and choosing the "Open in 32-bit mode" option if it exists.

Similar to the kernel having two modes, many applications that were migrated to 64-bit code may also contain a 32-bit version of their executable. Apple has kept both kernels in the past three major versions of OS X (Leopard, Snow Leopard, and Lion), but has switched fully to a 64-bit kernel in Mountain Lion. The reason for the 32-bit and 64-bit versions of the system kernel is that some programs require a specific kernel extension that might only be available in either mode, and therefore require a restart to load and work properly. You will notice that if you boot in 32-bit mode then the kernel_task process kind will be listed as "Intel" in Activity Monitor, but if you boot in 64-bit then this process will be listed as "Intel (64 bit)." This is why they show up as such in Activity Monitor, and it only means that the developer coded them in either 32- or 64-bit. In OS X, regardless of whether a 32-bit or 64-bit kernel is loaded, the system will still be able to run other processes such as your applications and background services in either 32-bit or 64-bit. "64-bit mode" as mentioned in the article only pertains to loading a 64-bit version of the system's kernel process (the core of the OS) and subsequent extensions for this process.
Your computer's processors are 64-bit, and therefore are always capable of running 64-bit code in addition to 32-bit code. Simply rebooting your system will restore the default 32- or 64-bit mode, and what you see in Activity Monitor is normal. It says No to the 64-bit Kernel and Extensions, but in the Activity Monitor under KIND, most, but not all, say 64 bit. If you do that, do you need to do anything to get it back out of 64-bit mode? I have a MacBook Pro, 2.33 Ghz Intel Core 2 Duo, 2GB 667MHZ DDR2 SDRAM that I did that on.

In your July 11 article "Older 64 bit Macs out of the picture", you told how to force boot into 64-bit mode.
