Spin Through Toolbar View Options

Although many people never change their toolbars from the default settings, all standard toolbars on the Mac offer six states: icon only, text only, and icon and text, with all three coming in normal and small size. You can change them by choosing View > Customize Toolbar.

But there's a shortcut that makes it easier to check out each variant. Simply Command-click the toolbar lozenge at the upper right of a window, and the toolbar switches to the next view. Click it enough times, and you cycle back to the start.

 
 

Older Mac Pros Toxic or Just Smelly?

Send Article to a Friend

A TidBITS reader in France who wishes to remain anonymous has alerted us to a tempest brewing around older units of the Mac Pro line. Apparently, users noticed a strong smell emanating from the machines, particularly when they were new, and the French newspaper Liberation just published an article about the experiences of a lab researcher who reportedly analyzed the emissions and found volatile organic compounds, including benzene, a known carcinogen.

AppleCare representatives in France contacted by our reader confirmed the problem as affecting Mac Pros built before 2008 but refused to put it in writing. Apple spokesman Bill Evans told Macworld, "We have not found anything that supports this claim, but continue to investigate it for the customer."

Apple's discussion forum contains posts from 2007 from users who experienced the smell, some of whom had their Macs replaced under AppleCare. In some cases, the smell may have been related to a seal near the power supply, small plastic strips on the access door, or the thermal compound on the processor heat sinks. Many, though not all, of the affected Macs were built in China.

The discussion thread started by our reader (reportedly after having several previous attempts deleted by Apple) hasn't generated nearly the number of "me too" posts as the 2007 threads, although some Mac Pro users who haven't experienced the smell are expressing concern.

It's difficult to know what to suggest with regard to this issue. Strong smells coming from a computer aren't likely to be a good thing, although without careful analysis, it's impossible to know whether the compounds being emitted are actually toxic, and if they're being emitted in concentrations that could pose a health risk. Plus, the machines in question are nearly a year old at minimum, so if there was a manufacturing problem, Apple has undoubtedly addressed it months ago. There seems no reason to suspect current Mac Pro units, but if you have a pre-2008 Mac Pro that emits a strong smell, or did for some time when it was new, you may wish to contact Apple about it.
