After three months of shakedown, Mackinac, escorting a large convoy, departed the United States West Coast for Pearl Harbor on May 11, 1942, arriving on May 19, 1942.

First Pacific Tour
On May 22, 1942, the famous explorer Rear Admiral (retired) Richard E. Byrd and his staff came on board for an inspection cruise of U.S. bases in the South Pacific, debarking at Auckland on June 23 1942. She then headed to Nouméa on July 18, 1942. Byrd, because of his worldwide recognition, had been drawn out of retirement to represent the U.S. to the French colonies in the South Pacific who were nominally under the German-controlled Vichy government.

Next, \Mackinac was assigned the task of setting up a seaplane base at Takataka Bay on Malaita, begining operations on August 8, 1942 with nine plane detachment from VP-23 PBY Catalinas searching northward and westward for Japanese warships. After the US Navy defeat during the Battle of Savo Island during August 8-9, 1942, Mackinac departed for Espiritu Santo on August 12, 1942.

Departing Espiritu Santo for the Santa Cruz Islands on August 20, 1942. Arrived at Graciosa Harbor on Ndeni Island and began PBY Catalina operations and tending.

Early on the morning of 12 September 1942, two Japanese submarines surfaced at the harbor entrance to shell Mackinac and USS Ballard. The two ships retaliated, but neither side suffered damage. Afterwards, returned to Espiritu Santo on October 25, 1942, assisted rescuing survivors of SS President Coolidge that had struck two mines in the harbor entrance.

On November 12, 1942, Mackinac established an advanced seaplane base at Peou Bay on Vanikolo Island in the Santa Cruz Islands, and began tending an average of six seaplanes a day. Vice Admiral William F. Halsey. Jr. visited her at this location.

Afterwards, returnred to Espiritu Santo then departed in a convoy for the United States West Coast on July 9, 1943, arriving at San Francisco on July 25 1943. She then underwent a two-month overhaul at Mare Island Navy Yard.

Second Pacific Tour
Mackinac returned to Pearl Harbor on September 28, 1943. After a month of transport duty between Midway and Maui, Mackinac left Pearl Harbor on November 20, 1943 escorting USS Curtiss (AV-4) to the Funafuti.

When a PBY Catalina flying boat was forced down near Nui in the Gilbert Islands, Mackinac, after locating it early on November 24, 1943, rescued the crew and safely towed the plane to Nuku Fetau despite adverse weather. On 1 December 1943 she arrived at recently secured Tarawa to tend seaplanes there through January 1944, undergoing 22 air raids during her time there.

Mackinac then steamed for Makin with Patrol Bombing Squadron 72 (VPB‑72) to participate in the Marshall Islands campaign with around‑the‑clock seaplane tending. Next, Mackinac was ordered on to Kwajalein anchoring there on March 9, 1944. While her patrol bombing squadron was conducting rescue operations at Majuro, Makin, Eniwetok, and Kwajalein, Mackinac was laying out the seaplane area and assisting the construction of a naval airbase on Ebeye.

On 23 June 1944, Mackinac departed for Eniwetok en route to Saipan and under constant Japanese fire while stationed there.

Relieved at Saipan on 19 August 1944, Mackinac joined seaplane tenders USS Chandeleur (AV-10), USS Pocomoke (AV‑9), USS Yakutat (AVP‑32), and USS Onslow (AVP‑48) bound for Kossol Passage, Peleliu arriving on September 15, 1944.
