Reclaim some wasted HD on MacOS X

  • english
  • spanish

Two useful MacOS X utilities:

  • AppCleaner: it helps you to completely uninstall applications from your system. When you install an app it copies several files (like plugins, extra libraries, etc.) outside the Applications folder, but those files don’t get deleted when you drag the app to the trash can. But I think that the best way to describe AppCleaner is saying it’s a free AppZapper clone. :) It looks exactly the same, same interface, same functionality, usage, everything.
  • MonoLingual: both the MacOS X system itself and almost every app you can think of come with translations for a shitload of foreign languages, which are a waste of hard drive space if you’re not going to use them. Besides, nowadays almost every binary is a “Universal Binary”, which is just a package with an Intel binary and a PowerPC one. Even more wasted space. MonoLingual allows you to remove every language you don’t need, and the binaries for the architecture you’re not going to use. Or like with AppCleaner: it’s a free Xslimmer clone. Just to get you an idea: after removing all translation files but the Spanish and English ones, and the PowerPC binaries, it has freed 2.5Gb from my system.

VMWare to Virtual Box: vmdk2vdi

  • english
  • spanish

I’ve been playing around a little bit with the MacOS X port of Virtual Box, and it looks really promising. Speed-wise it runs quite OK, I couldn’t tell wether or not it’s on par with VMWare Fusion. But I’ve had small problems with the keyboard (couldn’t get the alt and command keys to work right) and the “desktop resolution resizing” when in windowed mode.

Following these instrucions,  I’ve made a small shell-script that converts a .vmdk disk image file from VMWare to a .vdi one for Virtual Box. It should detect the OS (Mac or Linux) and warn you in case you miss some of the dependencies (QEMU ’s qemu-img and Virtual Box’s vditool). It can be downloaded here:

MacOS X firewall management

  • english
  • spanish

Via Applesfera I’ve learnt about two applications developed by Hanynet that allow you to manage the internal firewall on MacOS X Leopard:

  • NoobProof, easier to use for the average user, and
  • WaterRoof (cool name XD), more detailed, for the technically-savvy

Very useful.

MacOS X Games with Intel/Universal binaries

  • english
  • spanish

I’ve found a web with a list of MacOS X games and what hardware they support: if only PowerPC binaries are available (and then, how they perform under Rosetta), or if Intel or Universal Binaries have been released:

Besides, if you have problems while applying one of those patches to avoid the burden of inserting the CD everytime you want to play ;-) (the patch just quits and an error window pops up), you can fix it this way:

  •  copy the patch to your hard drive
  • right click (or ctrl. left click) -> Show package’s contents
  • go to the Contents/MacOS folder
  • replace the iPatcher binary with this new one (mirror)

iPatcher fix for Leopard found on Wildan Aliviyarda’s page. :)

Vintage computer and console emulators for Mac

While looking for an Amstrad CPC emulator for MacOS X, I’ve stumbled upon the following page with lots of vintage computer and console emulators for OS X:

MacOS X VNC Server

  • english
  • spanish

MacOS X comes with a VNC server, but it has problems: you can’t access it depending on what client version you’re using, and it seems to work only on full-quality mode (32bit color?), so it’s slow like hell.

An alternative is installing the marvelous Vine Server,which on its 3.0 release brings full client/server clipboard integration and works like a charm with any Linux VNC client, fast and without problems.

Weird CPU load spikes on Leopard

  • english
  • spanish

I was quite upset since yesterday because of this: a little while after booting my MacBook, CPU load went up over 50%, always. It was easy to detect because, besides the system being less responsive, FanControl put the fans over 5000rpm which makes a lot of noise.

The “Activity Monitor” showed that one of the two cores was always running at 100% and the other had the usual load, so the average was around 55-60%. However, none of the tasks on the task list table was over 4-6% CPU. No idea who was to blame.

I tried removing every gadget I had (like Growl, iScrobbler, InsomniaX…) from the start-up items, even rebooting and logging in with a “clean”, new user. Just the same.

Today I’ve tried directly with the terminal, and with ps have discovered that syslog was running at 100% CPU, so I knew where to look: on /var/log, the last system.log was over 250Mb while the previous ones (after bunzip2-ing) weighted less than 10Mb each. The file was full with AppFresh’s errors, not that important but they had this nasty side-effect. After killing syslogd CPU levels went back to normal, but the system re-launched it and CPU use spiked again. Removing the last system.log file wouldn’t solve the problem, either.

So with a clearer idea of what was going on I googled about it and found this post with a comment that suggested lowering the max allowed size for the asl.db file (mine was almost 50Mb). I’ve followed these instructions, killed syslogd again, and problem solved! My MacBook is as silent and resonsive as before. :)

iScrobbler and audiobooks

  • english
  • spanish

If you listen to audiobooks on your iPod you wouldn’t want to get that data submitted to last.fm with the rest of the music mp3 files. iScrobbler 2.0 has a series of hidden configuration options accessible from the terminal, and there’s one to filter the tracks by name or id3, so all you’d have to do is tag your audiobooks with the appropriate genre.

I’m using the following filter and it’s working great for me (copy-paste this line on a terminal to activate it):

defaults write org.bergstrand.iscrobbler “Track Filters” ‘("Speech", "Audiobook", "Audiobooks", "Audio Book", "Vocal")’
