What Dubuque Residents Say About Us

Real feedback from local residents, students, and small business owners.

★★★★★

"My 2017 MacBook Pro was painfully slow and throwing pop-ups every time Safari opened. CheckMac installed a 1TB SSD, cleaned out all the adware, and it literally boots in 8 seconds now. Saved me over $1,200 on buying a new Mac!"

A few things worth knowing.

Common questions regarding our repair services, warranties, and turnaround times.

Yes, in most cases! Upgrading an older MacBook with a modern high-speed NVMe solid-state drive (SSD), extra RAM, and a fresh battery costs a fraction of the $1,200–$2,000 price tag of a brand-new laptop. It extends your computer's lifespan by 3 to 5 years for everyday tasks, web browsing, office productivity, and schoolwork.
No. Our primary priority is data preservation. During virus, malware, and adware cleanings, we surgically target the infected files and registry/system entries while preserving your user documents, pictures, and desktop files. When performing SSD upgrades, we execute a complete, bit-for-bit clone so everything looks and acts exactly as you left it — just much faster.
No. CheckMac is an independent local computer repair and hardware upgrade facility located in Dubuque, Iowa. We are not owned, affiliated with, authorized by, or endorsed by Apple Inc. or Microsoft Corporation. This independence allows us to offer cost-effective component-level repairs, memory upgrades, and upgrades that authorized dealer stores often refuse to perform.
All hardware repairs and upgraded parts installed by CheckMac carry our comprehensive 90-Day Parts & Labor Warranty. If an installed replacement part or upgrade exhibits defects under normal use within 90 days, we will replace it or rectify the issue at zero extra cost to you.
Yes, absolutely! In addition to MacBooks, we service all major brands of Windows laptops and PCs, including Dell, HP, Lenovo, ASUS, Acer, MSI, and custom desktop gaming rigs. We handle SSD swaps, RAM upgrades, virus removals, screen replacements, and cooling system cleanouts.
Walk-ins are always welcome during our normal business hours (Monday–Friday 8:00 AM – 6:00 PM, Saturday 9:00 AM – 4:00 PM). However, scheduling ahead or calling us at +1 (563) 580-5888 allows us to reserve technician bench time for faster same-day diagnostic turnaround.

Let's see if it's worth fixing.

Contact our Dubuque repair specialists today for an upfront estimate or bring your computer in for an initial diagnosis.
