MacDonald then served in the United States with the 326th Fighter Group before transferring to the 348th Fighter Group to command the 340th Pursuit Squadron at Westover Field, Massachusetts.

On October 1, 1943, then a major, joined the 475th Fighter Group at Dobodura, New Guinea as the group executive officer.
He scored his first four victories that month and became an ace on November 9, 1943 when he downed two Zekes near Alexishafen Airdrome.
He was promoted to lieutenant colonel the following day on November 10, 1943 and became the group commander.

While he was CO of the 432nd Squadron, MacDonald demonstrated his leadership on an October 25th mission to Rabaul.
While leading a formation of P-38's flying escort for some B-24 Liberators on a Rabaul strike, heavy weather closed in, and all P-38's except MacDonald's flight turned back.
Suddenly, the weather cleared and the formation of B-24's, with hardly an escort, was attacked by  A6M Zeros.

MacDonald and his flight darted in and out of the bomber formation, clearing the Zeros from the bombers tails.
They couldn't spend time finishing off damaged enemy aircraft nor confirming kills.
Through their skill and diligence, they prevented many bombers from being shot down.
But another pilot could confirm one kill by MacDonald, a Zero, his fourth aerial victory overall.
For his actions, he was awarded the Distinguished Service Cross.

MacDonald moved up to Group Commander in Nov. 1943, replacing George Prentice who was rotated home.
Leading the group for 20 months, Colonel "Mac" flew his P-38, Putt-Putt-Maru, with the unit number "100."

During early April, he led the 475th on missions over the Japanese stronghold of Hollandia, in northwest Guinea; by the end of the month, it had fallen.

In mid 1944, General George Kenney arranged for Charles A. Lindbergh to visit and fly with the 475th.
He was able to teach the P-38 pilots to increase their operational range by 50%.
During his stay with the 475th, he and MacDonald became good friends, and earned MacDonald's respect as an excellent pilot.

On one interesting mission on July 28, 1944, he flew on an apparent milk run with MacDonald.
However, this "uneventful" mission became a sticky situation.
A Japanese fighter broke through their formation and set his sights on Lindbergh's P-38.
They were on a collision course, guns blazing from both airplanes, when at the last moment, Lindbergh pulled up.
The wounded Japanese fighter could not follow and dove into the sea.

General Paul Wurtsmith put MacDonald on a one-month "punitive leave" for allowing the national hero to get into a dangerous situation.
MacDonald returned to the 475th in time to lead the group during the momentous events surrounding the liberation of the Philippines.

He flew several sorties over Philippine Islands and shot down thirteen of his kills in the seven weeks between Nov. 10, 1944 and Jan. 1, 1945.
One of his most memorable missions occurred on 25 December 1944 when he destroyed three Japanese fighters over Clark Field in the Philippines.
He scored his last aerial victory on 13 March 1945, bringing his total to 27.

He finished the war with 27 confirmed victories, making him the third highest ranking U.S. Army fighter pilot of the Pacific Theater.
