Good, Inexpensive Laptop Feet

One of my favorite laptop accessories is/was made by an Oregon company and sold in local Mac Stores. They’re the ever useful and popular Dr. Bodelin’s laptop bumpers. The laptop bumpers raise the back end laptops up by about 1″ or so, dramatically increasing air flow thereby reducing internal and external temperatures. Ultimately, this can extend the life expectancy of a laptop. For $10, it’s a pretty good deal. Anyway, I recently needed a new set of silver laptop feet, so I called the Mac Store closest to me. I was mortified to find that they no longer carried the silver ones and that they only had white or gold. Gold?! Ugh. And white laptop feet on an aluminum MacBook Pro?? The horror. Being somewhat resourceful, I called Dr. Bodelin’s customer service line to see if the silver feet were really gone. Yup, confirmed. Not even a private stash at the company headquarters. Frak.

I did some Googling and found very few alternatives – some looked flimsy, some were bulky, some were plain ugly and they were all way too expensive for what they are – molded plastic nubs.
 

What to do…


Well, I found a very decent solution to my laptop foot woes. Two solutions, actually. I’ll demonstrate them below and you can decide which one you like best. First, a photo to show why laptop feet are a good idea.
 

As you can see here, the MacBook Pro has less than half a millimeter of airspace underneath. It’s part of Apple’s super sleek design, but it naturally restricts significant air flow.

I’ve used two 3M “Self Stick Rubber Pads” under the laptop and right next to the paper-thin feet Apple supplied.

Here you can see the MacBook Pro with the 3M rubber pads – the back is raised by about 1/4″. The pads hold up under moderate heat. Super warm laptops may eventually turn the 3M glue a little gooey. It takes a bit of heat, though. The 3M rubber pads cost $2.50 for 12 – enough for 6 laptops or 6 applications.

The solution I went with…


Here you can see a 3M “Command Strip” mini hook. These plastic hooks are clear, strong and easily support the weight of the 17″ MacBook Pro. They also have a somewhat cool shape. The tabs are removable and leave no residue. If you don’t want the little pull tab, it’s super easy to remove with a quick snip with some scissors.

The MacBook Pro is lifted by roughly 1/2″, providing extra air flow. The 3M mini hook is strong, gives a very comfortable angle of lift for ergonomic typing, etc. The 3M mini hooks are $3.50 for a set of 6, enough for 3 laptops or 3 applications.

Here are the two 3M packages. I got mine at The Container Store, but they’re available in lots of stores. And not to be too obvious, but #1 is the 3M rubber feet ($2.50) and #2 is the 3M mini hooks ($3.50).

Snow Leopard: Are your zip files not unzipping?

After updating my MacBook Pro to Snow Leopard, I noticed that I was unable to open .zip archives. I use The Unarchiver to open my Mac and PC-compatible archives. When I attempted to open a zip file, Unarchiver had been overtaken by Snow Leopard’s “Archive Utility”, and the Archive Utility.app kept freezing and required numerous Force Quits. I went through all kinds of debug actions, but nothing fixed the perplexing problem. I checked Google and found only one forum thread, but folks were suggesting that “Stuffit Expander” be used instead of Snow Leopard’s default utility. That’s not a solution, but a side-step around a critical booboo.

I recloned my hard drive and prepared to wipe everything and install a fresh copy of Snow Leopard. Literally on the verge of rebooting for the clean-sweep, I opened Disk Utility and ran the “Repair Disk Permissions” and “Verify Disk” functions.

Lo and behold, the zip archives are now opening with Snow Leopard’s built-in Archive Utility (which no longer freezes up). I re-installed Unarchiver and reset it as the default unzip app. All’s well, and I saved myself an evening of reinstalling all my apps. Phew!

If anyone else out there Googles “Snow Leopard won’t unzip” or “Archive Utility.app not working”, I hope they land here for the quick and easy fix.

Installing OS X Leopard in 10 Minutes from a USB Flash Drive

I decided to make a clean installation of OS X Leopard last night. I had already used Carbon Copy Cloner to copy my Leopard installation DVD to an 8GB partition on one of my USB memory sticks. Having the OS X installation DVD on USB is awesome.

At the tick of 5:44pm, I rebooted my MacBook Pro 1) with the USB memory key attached and 2) while holding the alt/option key down to select a boot drive. I selected the OS X installation partition and opted for the “erase and install” option.

The installation was complete and the system rebooted at 5:53pm. I got through the final setup screens and had the new OS X desktop under my control at 5:54pm. Total time: 10 minutes!

Why was this clean installation so fast? The USB flash memory to SSD flash memory data transfer is much faster than DVD to SSD, and dramatically faster than DVD to spinning HDD.

As a side note, when installing OS X from a flash drive, you don’t have to wait for the standard integrity check of the installation DVD – the verification effort is automatically skipped. I’ve always ditched that step anyway, but for those who allow verification to continue, a good deal of valuable time can be lost. Just another benefit of going all-flash.
