Review: Easy Upgrade For 2018 Mac Mini - Okay. So this just came today, and I installed it in about 30 minutes while watching the 9to5mac upgrade video and being extra careful. Everything was honestly very straight-forward and fairly easy for anyone who is comfortable with tools in their hand. The screws are, of course, small, and can take a steady hand. I highly recommend a magnetic driver for this. Also, I haven't read this anywhere yet, but I noticed that there was blue Loctite on almost every screw I removed, so I added a drop to each one of those screws before replacing. This may not be necessary, but Loctite is cheap, so why risk it? Blue Loctite is made hold things in place, yet still be removable. Once you remove a screw however, it should always be re-applied. Just because you can still see it on the screw, doesn't mean it's still going to hold. It's also very useful on anything else you may assemble that vibrates, moves, or bears weight. Basically any screw that you think has a chance of backing out over time. I personally don't want one of those tiny screws on my expensive Mac falling out internally and damaging/destroying electronics, so I'm surprised this isn't suggested ion any of the upgrade videos/articles I've looked at. I struggled the most with plugging the antenna cable back in (fingers too big?), but got it to go after a handful of attempts. I also used an iFixit tool kit that I purchased here on desertcart. https://smile.desertcart.com/iFixit-IF145-299-4-Driver-Bit-64pc/dp/B0189YWOIO/ref=sr_1_5?crid=385H6QIPQLVSQ&keywords=ifixit+essential+electronics+tool+kit&qid=1561248330&s=gateway&sprefix=fixit%2Caps%2C150&sr=8-5 This is a very solid tool kit that I will get a lot of use from. Highly recommended. This RAM was accepted instantly by my Mini and has made this thing blazing-fast. In summary, for about 30 minutes of your time and $130, you get $600 worth of factory speed on your new computer. If your clumsy, rich, or both - just pay Apple when you build your Mac. If you have a basic ability with tools, and a steady hand - this is a no-brainer. I'll definitely update this review if I see any problems with my computer going forward, but as of now, 5 stars.

It just works! *by L***. on February 12, 2024* I never have any issues with standard Crucial RAM, and it's my go to choice when upgrading a laptop or advising clients who are upgrading their systems. No frills or RGB lights, just consistent performance and reliability at a decent price. Given that RAM is one of the most important components to consider when building or upgrading a system, I steer clear of less expensive options from other companies. Crucial is a consumer / SMB brand of the company Micron, the world leader in memory manufacturing. ## Frequently Bought Together - Crucial 32GB Kit (16GBx2) DDR4 2666 MT/s (PC4-21300) DR x8 SODIMM 260-Pin Memory - CT2K16G4SFD8266 - SAMSUNG 970 EVO SSD 1TB - M.2 NVMe Interface Internal Solid State Drive + 2mo Adobe CC Photography with V-NAND Technology (MZ-V7E1T0BW), Black/Red - Dual Band Wireless- AC 8265 8265AC NGFF Wifi Card USE FOR Intel 8265 AC AC8265 8265NGW M.2 NGFF 2.4/5GHz Bluetooth 4.2 Wireless WiFi Card 867 Mbps --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/68657235-crucial-32gb-kit-16gbx2-ddr4-2666-mt-s-pc4-21300](https://www.desertcart.jp/products/68657235-crucial-32gb-kit-16gbx2-ddr4-2666-mt-s-pc4-21300) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-16*
