Preparing for Theft

Unfortunately, I’ve had several clients who have been robbed. The most recent was when a laptop was stolen from a car. There are some actions that you can take to avoid the worst outcomes if a theft does happen.

  1. Set Up Passwords:
    • Use strong, unique passwords or passcodes for both your device and your accounts.
    • Enable biometric authentication methods like fingerprint or facial recognition if available.
  2. Enable Remote Tracking and Wiping:
    • For smartphones, enable features like Find My iPhone (iOS) or Find My Device (Android). For laptops, use tracking software like Find My Mac (Apple) or Find My Device (Windows).
    • Set up remote wipe options to erase your data if the device is lost or stolen.
  3. Backup Your Data:
    • Regularly back up your device’s data to an external drive or a cloud service. This ensures you can recover your important files even if the device is stolen. Both Apple and Microsoft offer cloud backup services.
  4. Protect your Passwords
    • Especially important today, don’t let people see you type your phone or laptop login password. This “shoulder surfing” is now common before a theft. Once people can log in, they can change your password and actually lock you out of your accounts.

Don’t Buy a New Computer Now

There’s a saying that the best time to buy a computer is when you need one. WIth new technology always arriving, most jumps in technology are incremental. So just buy whenever.  Today, in August 2020, I suggest waiting a bit longer if you can.

Apple is leading the way to end of Intel-based computers with their announcement that they will start using “Apple Silicon” in their computers. This will be a huge jump for Apple’s computers and it portends similar changes that are surely coming to the PC.

Apple CEO Tim Cook Announcing Apple Silicon (aka ARM) for Macs

42 years ago in 1978, Intel came out with the 8086 chip and the x86 architecture. Intel, along with Advanced Micro Devices (AMD) later, made practically every computer’s central processing unit (CPU). (There were many exceptions such as Motorola 68000 chips and PowerPC CPUs, but these never achieved the scale or had the long run of Intel’s CPUs.)

ARM CPUs use a different RISC-based architecture than Intel’s CPUs, and became most ubiquitous in Apple’s iPhones and iPads, as well as most Android phones. Apple will start selling Macs this year with ARM CPUs, which Apple refers to as “Apple Silicon,” justifiably since Apple puts a great deal of effort into designing and optimizing the CPUs for their devices.

ARM is already becoming popular in servers. Therefore, we only await Microsoft Windows’ move to ARM for a full transition away from the Intel era. (Microsoft Windows does have an ARM version, but it is not 64-bit and was never made to be able to run the x86 applications.)

What does an ARM CPU mean for consumers? Due to efficiencies of the ARM CPU, we will see computers that are faster, smaller, and cheaper, while also having better battery life. This is partially because Intel has hit technical snags which have kept their CPUs stagnant the last few years. While AMD has made great improvements with their Zen chips on the same x86 architecture, ARM chips are clearly the power per watt leaders of the future.

So certainly buy a new computer if you need one now. But a big jump in computing is on the way.

Upgrade iMac to Fusion SSD for Speed

TechDC iMac 27” 2017  HDD to SSD (should work if there’s no fusion too)

I recently upgraded a 2017 iMac with a Fusion drive (SSD plus hard drive) to an SSD only Fusion drive by replacing the hard drive (HDD) with an SSD. While the idea of a fusion SSD may sound weird, it works great. The SSD in iMacs (especially 2017 and beyond) are much faster than a standard SSD, so you still get the fusion benefit of combining a faster and slower drive. And replacing a HDD with SSD is a huge speed improvement that can make a computer feel much more responsive.

Parts List

Crucial 2TB SSD ($207) – this is a hair faster than the Samsung.  

Or

Samsung 4TB SSD ($400) – not a lot of 4TB options on amazon

iMac adhesive strips + opening wheel

Generic phone and iMac work kit (has the necessary plastic cards and scraping tools and many other parts not used)

3M pads to adhere SSD inside iMac

Preparation Steps (note that a colon on a step means its a terminal command)

Step – Backup via Time Machine (to be restored later)

Step – Create a macOS (Mojave) boot usb drive (9to5Mac Article)

Step – Boot off usb drive (hold option key) and secure erase the HDD.  Since the HDD will be left inside the iMac, best to be safe and securely erase it.

Step – Launch Terminal from top menu Utilities 

Step -: diskutil list (to determine the name of the synthesized fusion disk drive such as /dev/disk2)

Step -: diskutil secureErase 0 /dev/diskX (where diskX is the name of the disk to HDD) (This can take hours depending on your drive size) (this does a single pass of zeros written for security, there are options to do more)

Installing SSD Steps 

Based on https://www.ifixit.com/Guide/iMac+Intel+27-Inch+Retina+5K+Display+Hard+Drive+Replacement/30522

& https://www.ifixit.com/Guide/How+to+Add+An+SSD+To+The+27-Inch+iMac+(Late+2015)/67309

Step 1 – Lay iMac on its back 

Step 2 – use roller tool to cut thru glue

Step 3 – use plastic cards to separate remaining glue (takes time and work)

Plastic Cards

Step 4 – lift up screen ad prop up with boxes

Step 5 – unplug old HDD

Step 6 – plug in new SSD

Step 7 – attach adhesive strips to SSD and stick to iMac wall, as near HDD as possible.  Slight angle is needed for opposite corners of SSD to touch curved wall.  I only put adhesive strips on opposite corners of the SSD.

Step 8 – move prop up boxes to inside the iMac so you can do the next step

Step 9 – remove all adhesive that held screen in place (takes the most time)

Step 10 – use alcohol wipes to clean up where the strips go

Step 11 – apply new strips

Step 12 – lower screen back down to adhere to new adhesive strips

Step 13 – Boot up iMac and begin post install steps

Post Install Setup Steps (colons refer to terminal commands)

Step 14 – Boot off macOS usb drive by holding down Option

Step 15 – Launch Terminal from top menus

Step 16 -: diskutil list (to determine the names of the old internal SSD and new added SSD)

Step 17 -: diskutil coreStorage create fusion /dev/disk1s1 /dev/disk0s1 (where disk1s is the faster internal SSD and disk0s1 is the new SSD

Step 18 – a unique UUID will be displayed identifying the new volume group.  Copy this to clipboard.

Step 19 -: disktuil coreStorage createVolume UUID-FROM-PREV-STEP jhfs+ “Macintosh HD” 100% (This note is likely changing those quotes to evil quotes, you’ll want to type this up with non-evil quotes so a reader can copy them)

Step 20 – open disk utility

Step 21 – Erase the new Macintosh HD with the APFS option

Step 22 – Restore from Time Machine

Step 23 – Open Photos (does restoration for a long time)

Step 24 – Open Mail (does some migration)

Cheap Comcast for the Poor and Veterans

Comcast has cheap internet for people who get government housing or food assistance, and now also offers this for Veterans. For $10/month you get 15Mbps/sec download and 2Mbps/sec upload. This is 10x faster than the old DSL speeds and more than fast enough for streaming HD video. There are no charges for setup or equipment (modem/wifi router). If you qualify, it’s a great deal.

Go to:
https://internetessentials.com

Or call 855-846-8376

To qualify, you can’t have had Internet through Comcast in the last 3 months and you can’t have another Internet service.

I only wish this was promoted more, as there are lots of qualified people who have big $100/month bundle deals because they don’t know other options exist.

Through the Internet Essentials website from Comcast, customers can also order $150 computers. These are slower desktops and laptops (currently with Core 2 Duos and i3 CPUs) but they come with Windows 10, Office, and Norton Antivirus preinstalled. This is also a great deal if you qualify. Each household has up to 2 years to purchase the computers and can purchase up to 3 computers. CDI is the partner that runs the computer sales and they can be reached at 888-234-4272.

When to Upgrade to a New Computer

New iMac

Clients regularly ask me when they should upgrade their computers. Most businesses upgrade desktop computers every 4-6 years and laptops every 2-4 years. But how often should you upgrade? Here are some factors to consider:

  1. Computer Release Cycles. It is typically best to buy a new computer model early after it is released. This can give you the latest technology and a longer product life. If a new model is just around the corner and you aren’t in dire need, consider waiting.
  2. CPUs. The Central Processing Unit is a key component and is usually made by Intel. A new model will often be released to coincide with the latest intel CPUs (and associated motherboard, RAM, etc). Buying the latest CPUs can mean that the computer will typically allow operating system updates for a longer period.
  3. Hard Drive (HD) versus Solid State Drive (SSD). I strongly recommend SSDs over traditional hard drives. SSDs do not have a spinning platter. They’re more energy efficient and super fast. Many people will find this gives the greatest perceptible difference in speed. Most new computers and all new Macs have an option for an SSD or a hybrid option that uses both an SSD and HD for improved performance (Apple refers to this hybrid option as a Fusion drive).
  4. Usage. Heavy computer users such as graphics designers and developers will find it more useful to upgrade quickly than people who mainly edit documents and use a web browser. Consider if the efficiency of your work would improve enough to warrant an upgrade.
  5. Hassle. Upgrading, especially on PCs can be annoying and take a great deal of time to configure the computer as you like. Macs are easier to upgrade, especially if you have an Apple store nearby. They will upgrade you for free and move over all your files.
  6. PC or Mac. A sad situation that I regularly see is a PC user upgrading after their computer has been infected by a virus. This makes some sense. If the computer has been compromised and is already a few years old, it could be considered “totaled” if the money and time spent on wiping the computer and reinstalling the operating system would be better spent on a new machine. Because of this, I often recommend that people consider Apple computers (Macs) if their needs don’t include Windows specific software. Macs in my experience don’t get viruses, don’t need additional antivirus software, and tend to have higher quality parts that last longer than the typical PC. Because of these factors, Macs have a lower total cost of ownership in my experience, despite having a higher initial cost.
  7. Security. If you have a Windows 95/98/XP PC or a Mac that is around 8 years old, you should consider an upgrade for security reasons. If your computer can’t upgrade to the latest operating system or latest web browser, then it won’t have the latest security patches and could be vulnerable to attacks.
  8. Deals. PC deals come and go all the time from Dell and others. Apple has one sale a year on the day after Thanksgiving, Black Friday. Apple does offer Education and Refurbished deals. Some Apple resellers offer minor deals, especially on older products.
