Hard drive cable failure is almost guaranteed to be your problem. We have a deployment of around 70 2012 13" MBPs for staff members, of which around 10% have had a hard drive cable failure. I had a suspicion you were going to say you had the same model from the symptoms you described. The symptoms on our problem MacBooks are exactly the same as yours with ...

Here's great article about this subject. More cores, slower clock speed Pros Applications that support multi-threading will greatly benefit from having a higher number of cores at their disposal Increasing the amount of cores in your CPU is a cost effective way of increasing performance Multi-threading support for applications will ...

Upgrading to 8GB will give your more memory-intensive applications a bit more headroom and allow them to avoid unnecessary swap-file usage. Upgrading to an SSD will give a more substantial speed boost overall - apart from dramatically improved OS and application startup times, any applications writing to and reading from a swap-file will also see ...

Since I have a much newer system I couldn't accurately test with a 119 MB file as it took less then a second to copy in Terminal. So I created several much larger files, up to 2 GB, using dd and /dev/random as the source and made duplicates. I then rebooted and then did timed copies of each of the sets, one in Terminal and the other in Finder. This way ...

It will likely run higher than 2.4 GHz in bursts and then throttle itself as heat builds up and/or all cores are busy constantly at which time you should expect full load 1.1 GHz or better. So - it will run at both speeds and many others. There is no indication that the Intel CPU works any differently in the MacBook than all the rest recent Mac hardware. ...

There may be a way to view your CPU's clock speed at this exact second, but as mentioned elsewhere, it is a constantly changing variable (due to Turbo Charge). Comparing clock speeds between different CPU generations, especially nearly five years apart, is also not at all useful. A much more useful approach would be to use benchmarks. MacWorld uses ...

Intel Power Gadget can show the current CPU frequency.

To answer this question accurately, you will need to get some statistics on how much RAM you are currently using. But in general, more RAM is going to improve things, especially if you're still on 4GB. On the other hand, the 2009 iMac is really reaching EoL at this point -- according to Mactracker, the support status for that machine is currently "Vintage". ...

The TRIM command was introduced to facilitate “garbage collection” of deleted data, allowing the SSD to reset those “unused” blocks back to an “empty” state. This allows for better performance for many SSDs. All Chameleon does is hack your SSD to enable TRIM. What the hack does is basically tell the OS that the non-Apple SSDs in the system are Apple drives ...
