After Windows XP

Given that Microsoft is no longer providing security patches to Windows XP, many users have a choice on what to do with these old computers:

1) Upgrade to Windows 7 or Windows 8. Download the Windows 7 Upgrade Advisor from Microsoft to see if your computer can run Windows 7. If it does, you can consider this option.

2) Get a new computer. Most companies upgrade computers every 4-5 years. If you’re running Windows XP, your computer is at least this old. Therefore, money spent on upgrading the computer might be better spent on a new computer that will have all new and improved components. Hard drives eventually die so it is possible that there may not be much life left in the computer.

3) Just keep running XP. While some security analysts are afraid of unknown future attacks that could be coming to XP, other security experts say that this is vastly overblown. The majority of attacks lately have been against applications (Java, Flash, Acrobat) that run on the operating system, not the operating system itself. Take some precautions with this approach. Make sure Windows Firewall is enabled. Run anti-virus software. Because Microsoft isn’t patching Internet Explorer on XP, use a non-IE browser such as Firefox or Chrome. Think about what you use the computer for. If your job depends on the computer, continuing to use XP is more risky than if you are just using it as a kids play computer.

Update to Paperless Office Post for OS X Mavericks

One of our most popular posts is Paperless Office in a Snap explaining how to set up automatic OCR of scanned documents.

With the release of Mac OS X Mavericks, the controls for Accessibility features have changed. Therefore Step 5 in the Paperless Office in a Snap post has changed. Instead of clicking Enable access for assistive devices under System Preferences – Universal Access, you now need to do the following:

Go to System Preferences – Security & Privacy – Privacy – Accessibility.

Click the checkbox to allow Folder Actions Dispatcher to control your computer as shown below.

ADDITIONAL UPDATE: This option might not show up for you until you go through the other steps in the original script and it fails. Then come back here and the checkbox option below should be available.

Upgrading Windows HD

I recently upgraded a client’s computer from an old spinning hard drive to an SSD (solid state drive) to make the machine much faster. A simple disk clone did not work for Windows 7 to make the disk bootable. To make Windows 7 boot properly, the SID (Security Identifier) had to be updated. This is done easily using Paragon Partition Manager by just checking off the option to change the SID after performing the disk copy.

2011 Mac Mini Hard Drive Upgrade Video

We just upgraded a 2011 Apple Mac Mini to have an SSD, a second hard drive, and new RAM.

Video

Also available on YouTube in High Definition or Standard Definition.

Parts List

OCZ 120 GB Vertex 3 SATA III 6.0 Gb-s 2.5-Inch Solid State Drive VTX3-25SAT3-120G
Western Digital 1TB Blue WD10JPVT 5400RPM, 8 MB cache, 2.5 inch, 9.5MM height hard drive
Corsair 8 GB DDR3 Laptop Memory Kit CMSO8GX3M2A1333C9
Apple Mac Mini Model MC816LL/A 2.5 GHz Intel Core i5 dual-core processor, AMD Radeon HD 6630M graphics, 4GB RAM, 500GB hard drive
Cable: Apple Part 922-9560, also called “Apple Mac Mini Server (Mid 2010) Bottom Hard Drive Server Flex Cable” or “Hard Drive Flex Cable Bottom”. We used part number 1009005 at welovemacs.com. This is sold as a kit from ifixit.com.

Alternate Parts List

The OCZ Vertex 3 is the fastest consumer SSD at the moment. Other SSD’s that you might consider include:

Highest reliability SSD: Intel 510 Series 120 GB
Best value high capacity SSD: Lexar Media Crucial 512 GB m4

The Western Digital Blue drive mentioned above is high capacity and quiet. For a faster spinning hard drive consider:

Western Digital 750TB Black WD7500BPKT 7200RPM, 16 MB cache, 2.5 inch, 9.5MM height hard drive

The dedicated graphics in the mid-tier Mac Mini make it worth it for me. But for the cheapest Mini, consider:

Apple Mac Mini MC815LL/A 2.3 GHz Intel Core i5 dual-core processor, integrated Intel HD Graphics 3000, 2GB RAM, 500GB hard drive

UPDATE: My video shows adding two 9.5MM height drives. I just upgraded another Mac Mini with a 9.5MM SSD and a 12.5MM standard hard drive. As with my first upgrade, the hard drive goes in the bottom slot (the side closest to the top of the case when upright). This does fit. But first you need to slide the logic board out slightly. Be sure to remove the IR port adapter before sliding out the logic board. The OWC video shows how to do this. I used a cut up coat hanger to insert into the logic board holes and slide it out.

First Boot

Starting with a blank hard drive is easy on the 2011 Mac Mini. Hold down Command-R to boot into Lion Recovery which allows you to format the drives and download Lion over the Internet.

TRIM Support in Lion

For optimal SSD performance, enable TRIM support within OS X Lion. Grant Pannell describes the terminal commands to enable TRIM.

Accidentally put an SD card in the iMac’s DVD drive?

Apple usually puts a lot of thought into the design of their hardware. However, the placement of the SD card slot right below the DVD drive has always escaped me. I always suspected people are looking directly at their screen and put the card in the slot by feel. As a result, it is probably all too common to accidentally put the card in the DVD drive which is right above it. I recently saw this happen for the first time.

My first thought was to take apart the iMac including the DVD drive. Unfortunately, this requires specialized tools and 1-2 hours of time. I tried shaking it out (a scary thought with an expensive piece of hardware) but it didn’t budge because of the foam guards at the end. Finally, I created a high tech tool just for the job.

This is a piece of cardboard cutout to have a little extension at the bottom. I inserted this at the top of the drive and pushed as far back as possible. I then slide it down and pulled it forward and the extension pushed the SD card right out. This is a rather thin piece of cardboard which is probably necessary. Be sure to be gentle as you don’t want to damage the DVD drive in any way.
