Omarchy Hardware

2018 15-inch MacBook Pro with Omarchy

Eight release-specific owner accounts establish a usable Linux path, but suspend, graphics power, audio and fan control still demand T2-specific work.

Compiled from eight exact-model owner accounts: six on GitHub, one on CachyOS Forum and one on Reddit. Report mix: one Omarchy · two Arch Linux · two Arch-based · three other Linux Updated

MacBookPro15,1 is not enough to identify the year. The 2018 release uses 8th-generation Core i7-8750H, i7-8850H or i9-8950HK processors and Apple part-number families MR932, MR942, MR952, MR962, MR972 and MUQH2. Apple reused MacBookPro15,1 for the 2019 15-inch model.

Bottom line

This Mac can run Omarchy, and exact owners have working reports for the internal display, keyboard, trackpad, Wi-Fi, Touch Bar and USB-C video. The difficult parts are connected: Radeon power state, T2 audio, Thunderbolt and the Apple BCE input stack can all change what happens at suspend. Current owners have found working configurations, failed second sleep cycles and fallbacks that only mimic sleep. The upstream hybrid-graphics patch is promising, but it was still under review on the date of this profile.

Should you use or buy it?

If you already own this Mac, keep macOS recovery available, start with Omarchy's supported T2 path and test several lid-close cycles with the GPU mode, audio and peripherals you actually use. If you are shopping, the used price must compensate for soldered memory and storage, the butterfly keyboard and more Linux maintenance than a conventional PC requires.

Detailed findings

Install and boot

Working reports

Exact owners have reached Omarchy, Arch, CachyOS, Fedora, Linux Mint and Debian desktops on this release. In 2019, an Arch install required a custom kernel, an external keyboard and copied Apple wireless firmware. Omarchy's current Intel Mac path now installs the T2 kernel, audio configuration, wireless firmware, fan service and basic Touch Bar support.

In practice The installation path has improved substantially, but Omarchy's supported route still requires disabling Apple's Secure Boot and erases the drive. Preserve macOS recovery and any Apple firmware you may need before installation.

Desktop and graphics

Mixed results

Linux normally starts this Mac on its Radeon GPU. Exact owners have run Radeon-driven desktops, forced the internal panel onto Intel graphics and used Intel as the Omarchy compositor GPU. The Intel path cuts idle power, but the published T2 guide still lacks normal runtime Radeon power switching.

In practice Choose between the released stack's stronger discrete-graphics access and a lower-power Intel-only setup. The upstream hybrid patch restored Radeon offload and power cycling in project testing, but it was still under review.

Hybrid graphics passed upstream testing. The patch series restored Radeon power cycling, DRI_PRIME offload, suspend and external displays on both 2018 and 2019 revisions; it was still under review. Project source

Internal display and brightness

Working reports

Owners report the internal panel working with Radeon graphics and after switching the panel to Intel through gmux. One Linux Mint owner noticed no display-quality change after the switch.

In practice The panel works in both reported graphics modes. Brightness keys, True Tone and automatic color handling are separate features and are not established across every Omarchy configuration.

Keyboard, hotkeys and backlight

Mixed results

Exact Arch and current T2 reports establish the built-in keyboard and basic Touch Bar keyboard mode. A Linux Mint owner could use the Touch Bar but not its backlight control, and current suspend logs show the entire BCE-backed input stack can fail after wake.

In practice Normal typing is available after the T2 drivers load. Treat Touch Bar lighting and post-resume input recovery as separate checks.

Touchpad and pointing

Mixed results

An exact Arch owner used the built-in trackpad after loading the T2 drivers, and newer owners report ordinary desktop use. Force Touch and palm rejection remain below macOS behavior, while some suspend paths return with the trackpad dead or require gesture software to rebind.

In practice The trackpad works for basic pointing. If gestures or suspend matter, test them after several wake cycles rather than assuming a fresh-boot result will hold.

Sources 2018 15-inch MacBook Pro Arch installation guide, MacBookPro15,1 Arch suspend and wake log, 2018 MacBook Pro Debian suspend configuration, T2 Linux feature state, 2018 15-inch MacBook Pro specifications

Fingerprint and biometrics

Problems reported

Apple built Touch ID into the Touch Bar, but the T2 project lists the Secure Enclave as unsupported. The exact Linux Mint owner likewise reported no fingerprint login.

In practice Treat Touch ID as unavailable in Linux. The basic Touch Bar working does not imply access to its fingerprint sensor.

Sources 2018 15-inch MacBook Pro on T2 Linux Mint, T2 Linux feature state, 2018 15-inch MacBook Pro specifications

Wi-Fi and Bluetooth

Mixed results

An exact 2019 Arch guide got Wi-Fi working after copying Apple firmware and using NetworkManager with iwd. Current Omarchy automates the firmware path, and exact Linux Mint and CachyOS owners report working Wi-Fi. Other exact suspend work required reloading brcmfmac or keeping PCIe compatibility mode.

In practice Wi-Fi is achievable, but its firmware and power state are part of the T2 setup. Keep wired networking or phone tethering available during installation and after kernel changes.

Speakers, microphone and audio

Mixed results

An early Arch setup had to choose between audio and suspend. A current Fedora owner recorded repeated hard freezes near T2 audio warnings, while a Linux Mint owner had working but poor-sounding speakers and improved them with an EasyEffects profile. Another Arch owner traced wake failures through the Apple BCE audio path.

In practice Sound output can work without being stable or well tuned. Test speakers, microphone, ordinary idle use and repeated suspend together before relying on the machine for calls.

Camera

Evidence, no verdict

Apple specifies a 720p FaceTime HD camera, and the current T2 matrix lists cameras as working through the out-of-tree T2 stack. A current exact-model CachyOS inventory shows the built-in camera bound to uvcvideo, but none of the retained 2018 owner reports documents a video-call test.

In practice Project support is positive but not a release-specific camera result. Test the camera in the actual application and after suspend.

Sources 2018 15-inch MacBook Pro specifications, T2 Linux feature state, 2018 15-inch MacBook Pro lid resume on CachyOS

Suspend and resume

Mixed results

The reports span a working Intel-only Omarchy setup, a complex Debian workaround, repeated Arch failures tied to graphics, audio and BCE state, an Omarchy second-cycle hang and one successful five-minute CachyOS retest. One Arch fallback passed repeated cycles by suspending devices and immediately resuming instead of entering the normal sleep state, with higher battery drain.

In practice A screen that wakes once is not enough. Test several cycles with audio active, the intended GPU mode and the same docks you will use; until that passes, shut down before putting the Mac in a bag.

A model-tested graphics fix is under review. Patch authors report repeated suspend, resume and GPU wake tests on both MacBookPro15,1 revisions. Project source

External displays and docks

Mixed results

An exact Arch owner reported DisplayPort over USB-C working with a compatible adapter, and a current CachyOS inventory showed a 3840-by-2160 display at 60 Hz on Radeon. A shared-identifier report froze with one dual-HDMI dock. Newer project testing covered several Thunderbolt and USB-C monitors across Radeon power transitions.

In practice Video output works in reported setups, but a working USB-C adapter does not establish every dock. Test the complete adapter, cable, display, GPU mode and lid state you intend to use.

External displays worked in current patch testing. The Radeon GPU powered up for attached monitors and powered down after disconnection on both 15,1 revisions. Project source

Battery, power and thermals

Mixed results

One exact owner measured about one hour of light use on a new battery with Radeon active and about five hours after forcing Intel graphics. Another found that t2fanrd could not identify either fan. Patch authors measured about 24 watts at idle before their hybrid work, roughly half attributable to the unused Radeon GPU.

In practice GPU mode dominates the Linux battery experience, while fan control and low-drain sleep are separate risks. One repeated-cycle Arch fallback avoids real sleep and reports two to three times its normal sleep drain.

The patch removes the idle Radeon penalty in testing. With Intel graphics primary, the Radeon GPU entered DynOff and returned for offloaded work or external displays. Project source

Daily use

Check the processor or part number before buying

MacBookPro15,1 covers both the 2018 and 2019 15-inch releases

The 2018 processors stop at the Core i9-8950HK, and its Apple part numbers begin MR932, MR942, MR952, MR962, MR972 or MUQH2. A Core i9-9880H or i9-9980HK belongs to the 2019 release.

The graphics mode changes the whole laptop

One owner moved from about one hour to about five hours by disabling the Radeon GPU

That workaround improved light-use runtime on a new replacement battery but removed discrete-graphics access. The upstream hybrid patch targets the real compromise: keep Intel graphics primary, wake Radeon for offload or displays and turn it back off afterward.

Suspend is a stack, not a switch

Graphics, audio, Thunderbolt and BCE-backed input have each changed the wake result

The same model has resumed once and failed on a second cycle, woken without input and required a custom path that never enters normal sleep. Test the complete working configuration instead of changing one sleep setting in isolation.

Performance

Sustained CPU work

Fast bursts, followed by a meaningful cooling limit

The Core i7-8850H review unit scored 953 in its first Cinebench R15 multicore run and settled near 820 to 830 before Apple's launch-era updates. Its processor repeatedly approached 100 C. Later software improved stability, but the review still found that the chassis could not sustain the processor's full 45-watt design power.

Graphics work and older games

The Radeon Pro 560X scored 1,775 in 3DMark Time Spy and 40 frames per second in Fortnite at the review's high setting

Those Windows and macOS results show the optional GPU's hardware ceiling, not Linux performance. The released T2 stack makes discrete graphics costly at idle, and turning the GPU off for battery life removes it from workloads until the new hybrid path ships.

Travel and battery use

About 10.2 hours in the original macOS Wi-Fi test; about five hours in one current Intel-only Linux report

The exact Linux owner used a new replacement battery and moved from about one hour to five by disabling Radeon graphics. A separate Arch fallback passed repeated lid cycles only by skipping normal sleep, with two to three times the usual sleep drain. Neither establishes an Omarchy travel baseline.
