Thunderbird 2.0.0.21, opening attachment
Each time an attachment is opened and click again, it is loaded again and a new copy of the attachment appears even if it was already present. Not fun

Parallel 4 does not find the bootcamp partition
A conflict seems to occur between Macfuse and the NTFS-3G component and Parallel. Both cannot be run at the same time. Unmout the bootcamp volume before to use it in parallel.
To do that, select the partition and use cmd-E. If the partition is normal seen because its name bagins with ., use it on the latteral bar.
Back to the configuration, save the configuration and its run again

TimeMachine
From MacFixIt
Possible reasons and fixes for Time Machine slowdowns
Time Machine has been a great backup solution that has for the most part worked quite well; however it has not been without its glitches. Despite the majority of initial problems being addressed by Apple, there will be times when the backup process seems to just hang or stall out, without giving any apparent errors or notifications.
To easily check out Time Machine logs and track down problems and exactly what Time Machine is doing, download the "Time Machine Buddy" widget, which will display the TM logs in the dashboard.
Hanging may also prevent other operating system functionality, causing spinning beachballs and the inability to shut down when the backups are going. This type of behavior usually indicates the system resources are not accessible to the system when the system is expecting them to be. For instance, if an external drive is not responding as it should, the system may hang while it waits for a response from the drive. There are several reasons why a Time Machine drive may suddenly be inaccessible:
Drive malfunction.
If the drive is making clicking sounds, or doesn't appear properly either on the Desktop or in Disk Utility, then there may be a problem with the drive. For external drives, low power to the drive can cause the system to hang.
Volume corruption.
While the disk may be fine, if the formatting or partitioning of the drive has problems, then the drive will not be properly accessible by the system.
Drives being put to sleep.
The energy-saver setting to put drives to sleep whenever possible can cause them to go into a state where they won't wake up properly. This depends on the drive itself, but while the system waits for the drive, you can experience a hang.
For drive errors, you can try running Disk Utility to check for and repair errors on the drive, or you can more thoroughly do this with third-party disk utility software such as "Disk Warrior," "Drive Genius," "Disk Tools Pro," or "Tech Tool Pro." Checking both the boot drive and the Time Machine drive for errors is recommended.
Beyond drive-specific issues, there can be incompatibilities both with other system resources and third-party applications, which can cause Time Machine slowdowns. If you have antivirus software running, many times this can interfere with Time Machine's functions, especially if you have live scanning or "on-access" scanning enabled. Turning off these settings in the antivirus software may help this situation. Additionally, if you have spotlight enabled for the Time Machine drive (it is enabled by default), it can sometimes endlessly try to index the drive. As such, you can try adding the Time Machine drive to Spotlight's privacy list, and then remove it to restart indexing.
A similar thing can also be done in the terminal, which will ensure the spotlight stores are deleted and started anew:
Open Terminal
Type the following command and include a space after the command:
mdutil -E -i off
Drag the Time Machine disk to the Terminal window to enter the full path to the disk, such as the following:
mdutil -E -i off /Volumes/TMDisk/
Ensuring a space is between the "off" and the drive path, press enter
Repeat this command, changing the "off" to "on" in order to enable spotlight on the drive again.
Finally, if you are backing up over a network (especially a wireless network), backups can be slow by nature. At 54Mb, speeds of most wireless connections, you will run at a maximum of 6MB per second, which translates to 14 hours for a 300GB backup when running at optimal conditions. Given network overhead and other interferences, this can easily double and result in the backup taking a day or two. For the initial backup to a networked device, you might try plugging in the Ethernet connection, which should be at least double the speed, but up to 20 times faster than wireless.
An additional fix for slow backups can be to restart Time Machine on the drive by removing it and re-adding it in the Time Machine preferences. Doing this seems to clear various bottlenecks in Time Machine and start backups running at faster speeds again.

PRAM et SMC/PMU
From MacFixIt
When to reset the PRAM and SMC/PMU
The PRAM
The Parameter RAM is a small amount of "nonvolatile" RAM (NVRAM) that holds various settings that the system can use before the operating system loads, and maintains these settings even when the computer is turned off. There is a small battery on the computer's mainboard that helps maintain the PRAM settings when power is off.
Many times when people's computers get bogged down and they are experiencing problems, advice will be given to "Reset the PRAM." In certain situations this can fix things, but many times people just blindly throw that advice out there. Resetting the PRAM may sound like an exotic fix that somehow may magically cure something; however, many times doing this is just a shot in the dark. As such, it's not necessarily bad for the computer, but may lead to customized settings such as alternate boot devices and speaker volumes being put back at default values. If you have problems with any of the following then a PRAM reset might help you out:
Volume changes or won't stick.
Video resolutions not sticking or not all available
Time zone information and clock settings
Boot volume isn't set (question mark shows briefly before booting)
Keyboard repeat rates
Mouse input rates (click and tracking speeds)
Default system fonts
Prior to OS X, the PRAM held information for networking, but that has been removed so any network troubles should not be affected by PRAM settings. Sometimes there have been odd problems that have been cured by PRAM resets, including one reported on recently by MacFixIt regarding spell-checking not working. It is possible that settings in the PRAM may indirectly affect various system functions like the spell checker, but knowing this is anyone's guess.
If these settings constantly get reset even when you have not manually reset the PRAM, the computer's logic board battery may need replacing.
To reset the PRAM, reboot the computer and hold the options-command-P-R keys at the same time. The computer will chime, and then continually reset and chime while these keys are held. Allow it to cycle a couple of times and release the keys and allow the computer to boot normally.
NOTE: Resetting the PRAM may require you to set some settings such as mouse speed and keyboard rates again.
The SMC/PMU
The System Management Controller (Intel Macs) or Power Management Unit (PowerPC Macs) is a chip that manages the power for various system components such as the fans and backlights, as well as the circuits that initiates power to the whole system when you turn on your computer.
Like the PRAM, many people readily offer suggestions for resetting the SMC or the PMU. However, there are specific behaviors that will benefit from SMC/PMU resets, and others that won't. For the most part, the power management in the computer should only be reset if you experience problems with seemingly "stuck" settings, or nonfunctional indicators, especially any on the hardware itself (power adapter indicator, or battery life for laptops). The following list of situations are some instances where a SMC/PMU reset can be beneficial:
Battery isn't charging properly
Display brightness won't work properly
Keyboard backlight won't work
Fans blaring all the time
Power button not functioning properly
Closing/opening laptop lid doesn't sleep/awaken the computer
External ports not receiving power
External devices not recognized
Internal components such as Airport or Bluetooth not starting up
Unexpected shutdown

Des raccourcis peu usuels
From MacFixIt
(Command + Shift + L) - Opens a new Safari window and performs a Google search for highlighted text when performed.
(Command + Option + F) - Places cursor in the Google search bar in Safari.
(Command + Delete) - Moves the highlighted file (in Finder) directly to the trash--a great timesaver when deleting multiple files throughout your system.
(Command + Option + Control + 8) - Freaks your unsuspecting friends out by inverting the colors on their screen. This is actually an accessibility feature in OS X that helps vision-impaired users.
(Command + D) - Moves the directory to the Desktop folder when performed in Save, Save as, or Download windows. Most programs have a default save or download folder (or default to your last saved folder). This command is very useful when you are not sure where you want to save your file.
