About

Defrost Pro

Features
Read full description

Some Mac Pro (late 2013) users complain that their screen freezes sporadically. Sometimes several times a day. Other times this does not happen for several weeks. If your Mac Pro (or other Mac) suffers from screen freezes while the rest of the system is still running (sound is still being played and the cursor keeps moving and changing according to the underlying but frozen GUI), Defrost Pro can help you restart or shutdown your Mac. Just select the device that is having the problem from the list of devices in your current network and press restart. This will not save any unsaved file for you. But it will prevent having to hard shutdown the device and potentially causing any harm to the hardware or file system. Defrost Pro does not need to connect to the internet, but it must be connected to the same local network as the Mac to be restarted. Defrost Pro can only restart Macs running macOS. Nonetheless Defrost Pro will list all the devices in the local network. You need to know the ip address or the devices name to select the correct Mac. Requirements: - You will need to enter the device's admin name and password. Usually if there is only one user on the device that will be the admin. - The Mac to be restarted needs to have Remote Login activated so Defrost Pro can login and tell your Mac to restart. Activation can be done in the System Preferences under Sharing.

Skim Guard helps you check a card reader before you pay. It's free for shoppers. Card skimmers are small devices criminals hide on gas pumps, store registers and ATMs to copy your card. They can be hard to see. Skim Guard gives you a quick way to check before you swipe. How it works: Hold your phone near the card reader and tap to check. Get a clear answer: the reader looks fine, or it's better to use another one. See a map of where skimmers have been found near you, and where it's clear. Keep a history of every reader you've checked and what you found. A few simple habits also help: give the reader a quick look and tug, cover the keypad when you enter your PIN, and tap to pay when you can. If you use an EBT card, lock it in your EBT app between trips. Store owners can use Skim Guard Business to check their own readers every morning and keep a dated log. Learn more at skimguard.io.

Verdict

The call

The clearest difference is ads: Defrost Pro at none against SkimGuard's shown. Defrost Pro also leads on iOS requirement (10.0 vs 16.0). SkimGuard's advantage is update cadence (every 3 weeks vs every 2 months). On price, in-app purchases and device support there is nothing between them.
