If you ever had the misfortune of having a disk corrupted you know how bad it feels to lose your files. Here are some tips on recovering files on a Mac.

First, a word of advice. Before using your cards on photographic equipment, always format them so you make sure that you’re starting from a clean and well-structured drive. Failure to do so increases the chances of corrupted data and makes it messier to recover files later.

If you’re already in possession of a disk with corrupted data, you need a fix. I analyzed the following software packages in my evaluation:

• Easeus Data Recovery
• Recoverit
• Disk Drill
• PhotoRec and TestDisk

The first three are premium software packages, while the last-one is open source and is a command-line utility, so it might look a bit harder to use. If you have the patience to learn how to run software from the command line and you have time to read the manual, then you’ll be fine.

In fact, this is my favorite software for recovering files and fixing otherwise broken file systems.

From the other three software packages, only Easeus Data Recovery got me results as good as the PhotoRec and TestDisk combo. I would, therefore, recommend it if you want software that is user-friendly and does the job. I wasn’t impressed with the other two as they were either not that straightforward to use or didn’t recover files as well as my favorite picks.

Here are my notes on copying remote keys for your garage.

Some garage door companies lock the reception box so you cannot add any more remotes unless you go through them. This is what most people do anyway. It’s a perfectly valid way of going about things, but you give these companies the opportunity to charge you 50-100 euros when you can do it yourself for half price or less.

If you want to do it yourself, read on.

You will need to buy the HR Matic remote which is the best remote I found. You can buy it on Amazon or directly from the manufacturer and distributors.

Some remotes have fixed codes and others have rolling codes, which makes them harder to copy. You might need to open the receiver box in your garage and press a button on the board to add your new remote control to the list of allowed remotes.

I don’t like using Apple’s applications and proprietary file storage types for photos. I like it old school where I can just drag photos from my devices to my external drive in a folder and organize them manually via folders.

Storing photos on iCloud is a privacy concern that not many people care about, but I do so I prefer to avoid it.

I’ll therefore talk about how I manage the exporting process of images from my iPhone to my local storage.

iMazing Backup

A couple of years ago I started using iMazing Backup which is an excellent software for Mac that enables me to bypass the whole Apple silo by making my own automated backups of Apple devices we have in the family over Wi-Fi. So the main reason I purchased it was to have an iCloud backup alternative.

However, it is also an excellent manager for Apple devices. I frequently use it to drop PDF books onto my iPad, for example. The process is extremely easy.

Another use case for me is exporting images from my phone onto local storage. I like to keep my phone as clean as possible and export all my photos every month or so. The disadvantage is that I don’t have easy access to all my photos, but on the other hand I know that my photos are safe and backed up at all times.

iMazing Backup has an excellent photo and video expert utility that also includes some smart folders. You can read about how it all works on iMazing’s guide.

This tool lets me export all images including the live photos (which in reality are short video clips) as well as original versions of edited photos. You can also choose to automatically convert from HEIC to JPEG and also change the naming structure of the photos.

Image Capture (My Previous Method)

This had been my go-to method prior to starting to use live photos. I then realized that this method would not export the live photos but only the still version. So I had to stop using this method.

Here’s how to do that process to transfer photos from an iPhone to an external drive, or anywhere on your Mac for that matter.

1. Connect Your External Hard Drive To Your Mac. First, connect the hard drive to your Mac and make sure it shows up in the Finder’s sidebar.
2. Connect Your iOS Device To Your Mac.
3. Launch Image Capture.
4. Select Destination.
5. Click Import.

What to do if you already have your photos in the Photos app

If you had already used the Mac Photos app to import your photos from the phone, and you now want to export the individual photo files, you should follow these steps:

1. Launch Photos on your Mac.
2. Hold down the Option (⌥) key while dragging images to the Finder.

All of the original parameters of your images will be entirely preserved. In Photos 1.0, dragging an image out of the app would save your selection as a downscaled JPEG file. In the most recent release, dragged images retain their original resolution but are still recompressed as JPG files.

Note that I’ve had problems copying a whole album at once if it has a lot of photos in it. I’m not sure if it’s a general issue or just a local thing on my setup. What I do in that case is just select smaller batches of photos to move over.

It is very important for your site visitors and for SEO to have your site load fast.

Here are a few things I do to make things fast on my site.

Fast hosting: Kinsta

Content Delivery Network: Cloudflare

I use the following performance-related plugins:

• Perfmatters

Of course, it is also important to use quality plugins on your site. Quality is more important than quantity. Ignore people who just say that many plugins installed and activated slow down your site, it all depends on the quality of those plugins. Sometimes you install just 5-10 plugins and the plugin slows down immensely because of what those plugins actually do or how they are coded.

Manual optimizations worth mentioning

I like to set up cron via the server instead of WordPress cron. I also use Perfmatters’ script manager to selectively load scripts on every page of my site, instead of letting plugins load their scripts on every page indiscriminately.

Another optimisation that can be done where possible, is to avoid using third-party fonts like the Google Fonts, you can easily do away with them unless you have specific branding guidelines to follow. This will provide a further speed boost to your page.

Testing

I use the following tests to make sure everything is running smoothly:

• GTMetrix
• Pingdom
• Webpagetest.org
• Google Chrome’s Audit feature
• Google Analytics’ Page Speed feature

Also make sure that you test both the desktop and mobile versions of your site, as they might be loading different content and thus merit the need to be tested separately.

Hope those speed and site optimisation tips help, let me know if you think I missed anything.
