Back to the Mac 


It’s alive !! Although with issues, right now (and in the picture) the battery is not charging, actually, for the system it is not present. I think the problem might be a fuse that burned, I as thinking that the power center was defective and was not providing enough power to charge the battery, but more probably the issue is with the fuse and the SMC is preventing the power to reach the logic board, then battery is not charging.

So, under normal operation the battery is not charging and the power supply is not providing any energy, how is that the computer is on?. No, is not on the leftover of the battery. read more

What makes a Mac a Mac


I think that Macs are expensive computers, but any other computer with the same hardware should cost more or less the same.

Yes, you can get cheaper computers with the same processor, more storage and the same amount of ram, but is not just CPU-RAM-HDD what makes a computer a good computer. Is everything that is around those. read more

Accelerate your macports upgrade/install by using ramdisk

The main problem when compiling is the tons of disk access that compile involves from compiling, linking, stripping etc… if you have a regular hard disk you know this may take a lot of time, most if the project is large. If you have an SSD the problem is not the speed, but still the lots of read/write access even when SSDs are pretty much more reliable that they were years ago.

A simple fix  is to use ram disk. I’m not going to tell you how to do it in linux, because in linux you basically mount tmpfs in a directory and you are done, but in OS X this may be a bit tricky. In particular if we talk about macports. read more
