Introduction
Micah Sargent kicks off the episode by introducing the focus topic: an innovative application designed to help Mac users reclaim disk space without deleting any existing files. He emphasizes that this app diverges from traditional cleaning utilities by leveraging a unique feature of macOS to optimize storage.
"Welcome back to Hands on Mac. I am Micah Sargent, and today we are taking a look at a really cool app that will help you reclaim disk space on your Mac."
— Micah Sargent [00:26]
Understanding the Apple File System (APFS)
Micah delves into the intricacies of macOS's default file system, APFS (Apple Protected File System). He explains how APFS manages files and metadata, allowing multiple versions of the same file without duplicating the actual data. Using a relatable metaphor, Micah compares files and their metadata to a person changing outfits, where the base (data) remains the same while the metadata represents the different appearances.
"Think of the thing beneath the clothes as data. This is the information that makes up the base file... the metadata is the stuff that is happening to you right?"
— Micah Sargent [02:15]
Micah contrasts APFS with older file systems, highlighting that traditional systems create separate files for each version with different metadata, leading to unnecessary data duplication and increased disk usage.
Introducing Hyperspace: A Solution for Disk Optimization
Micah introduces Hyperspace, an application available on the Mac App Store, developed by HyperCritical. Hyperspace is designed to identify and consolidate duplicate data by leveraging APFS’s ability to handle multiple metadata versions efficiently.
"The app is called Hyperspace... it lets you look at the files on your system and find those instances where we can compress it down to one and just have the metadata that is linked in multiple places."
— Micah Sargent [04:10]
Demonstration of Hyperspace
Micah provides a walkthrough of Hyperspace’s functionality:
-
Selecting Folders: Users can choose specific folders (e.g., the home folder) to scan for duplicate data.
"I chose my home folder... It’s going to be handy for those who have transitions from older file systems."
— Micah Sargent [06:00] -
Scanning Process: The app scans selected directories to identify eligible files that can be optimized.
"I scanned 195 files, 32 folders... Potential savings: none."
— Micah Sargent [07:00] -
Reclaiming Space: Upon identifying duplicate data, Hyperspace offers options to replace redundant files with space-saving clones. Users can choose to move duplicates to the trash or permanently replace them with clones, thereby freeing up disk space without losing any files.
"It gives you the option to determine which files to make the source and replace the others with space-saving clones."
— Micah Sargent [09:30]
Pricing and Purchase Options
Micah discusses the pricing structure of Hyperspace, highlighting its flexibility:
-
One-Time Purchases:
- Monthly Unlock: $9.99
- Yearly Unlock: $19.99
- Lifetime Unlock: $49.99
-
Subscription Models:
- Monthly Subscription: $9.99/month
- Yearly Subscription: $19.99/year
These options allow users to choose between occasional use or continuous access, supporting the developer while providing value based on individual needs.
"You can unlock the app for a month at $9.99, a year at $19.99, or go for the lifetime unlock at $49.99."
— Micah Sargent [12:10]
Conclusion
Micah wraps up the episode by reiterating the usefulness of Hyperspace for Mac users, especially those migrating from older file systems or managing multiple file systems across different hardware. He encourages listeners to explore Hyperspace, available for free download with in-app purchase options, to optimize their Mac's storage effectively.
"Shout out to this really cool kind of niche app that I think is helpful to people who made the transition from older file systems into the new ones... Right there in the Mac App Store."
— Micah Sargent [14:00]
